E.R.T. Madjitey's career in the Police turned out to be the pinnacle of his life. If ever he turned out successful,  it stemmed from the two cardinal principles he strongly believed in:

i) never procrastinating and
ii) giving the best in whatever he did.

If ever there was a proponent of the concept, 'whatever is worth doing is worth doing well', it was Madjitey. Indeed so much did he believe in this cardinal principle that, despite the great pain he was suffering due to abscess in both legs he still went ahead an sat for his final school certificate exams in bed. He always used to maintain that if he had not adopted that attitude, he would never have turned out the first African (both in Sub-Saharan Africa and the whole of the British Commonwealth) to head a Police Force. If we his children had a dime for anytime we heard the phrase "Primus inter Pares", I am sure we would all be millionaires. 

This is however, not to say that the road to the top was not rough for him. He wrote in the script of "Behind The Scene" [a book he once contemplated writing]:

"The non commissioned officers and inspectors under whom we worked all seemed to have been briefed to sabotaged the scheme under which we were enlisted. I found most of them uncooperative and little mistakes we made were magnified out of proportion".

He always used to recount with great humor an incident which happened between him and a barracks Sergeant when he was stationed at Christiansburg, Osu as a constable:

" Our barracks sergeant was an elderly man called Batawule Lorso. He was popularly known as "Fowl Sergeant" because for a long time he had been employed as a caretaker of the Commissioner's poultry at the Police Training School. He and I did not get on too well because, he tried to show off and had little respect for educated men. One morning when I returned from night duty, he ordered me to go to the main barracks to attend morning parade which was due to start in 45 minutes. Fortunately I had a clean kit so, I hurriedly got ready and proceeded to the Central Barracks only to be informed there was no parade. I returned to Christianborg and an argument ensued between Lorso and myself. He immediately placed me on a charge of insubordination. Well aware of the fact that I might go to England for higher training, provided I maintained a good record, he was well pleased to have the opportunity of staining my record to the extent that he ignored all the pleas by my colleagues to drop the charge. This was a Tuesday and the charge was supposed to be heard on the next Friday. On Thursday, at about 10:30 a.m., I received a telephone call summoning me to report to the Commissioner of Police at headquarters. The first thing that came to my mind was the charge and I became very worried. I arrived at headquarters at 1:45 p.m. and fifteen minutes later, was marched to the Commissioner's office where he informed me that I had been promoted to the rank of Sub-Inspector. Of course on my return to Christianborg, there was no immediate sign of the sergeant".  A few days later he re-surfaced and apologized declaring "all that charge matter, ibe play" and that he had already destroyed the charge papers. 

Following his promotion to Sub Inspector, Madjitey was posted to Kumasi where he served for a year. Naturally he faced a lot of opposition from the European officers who were against the new Africanization policy. Nevertheless, in May 1946 Madjitey proceeded to Preston, United Kingdom on a scholarship which attached him to the Lancashire Constabulary for a years course in general Police duties. 

Upon return to the Gold Coast and after a short delay, he was promoted Assistant Superintendent of Police and posted to Takoradi (in the Western Region) as an Immigration Officer. In August 1948, he was transferred to the Accra to take charge of the "B" district and appointed honorary 'Aide-de-Camp' to the Governor of the Gold Coast. In 1949 he was transferred to Sekondi (also in the Western Region). The same year he married a student of the Krobo Girls Training College Miss Vera Korleki Scales.  

In 1952, Madjitey proceeded once more to the UK where he did the senior officers detective course with the London MEtropolitan Police in Scotland Yard. On his return in 1953 he was posted shortly to Tarkwa but returned to Sekondi as second-in-command of the  Western region. On December 1st, 1953 he was promoted Superintendent of Police. In 1955, he attended the senior officer's course at the Police Staff college at Ryton-on-Dunsmore in Coventry. On his return, Madjitey was posted to the Eastern Region as second-in-command. 

In 1956, he assumed command of (his native region) the Eastern region with the acting rank of Chief Superintendent thus becoming the first African to command a Police region.  The same year, he was nominated for the Colonial Commissioners course at Bramshill.

Upon completion at Bramshill, E.R.T. Madjitey was awarded a scholarship to the United States under the joint auspices of the United States International Education Program and the International Association of Chiefs of Police. In America, Madjitey was attached to various Police organizations including the FBI, CIA, Secret Service, Columbus, Ohio City Police, Grand Rapids, Michigan City Police and the Detroit City Police to mention a few. He returned to the Gold Coast after a year and took part in Ghana's independence celebrations in March 1957. He took charge of Accra Division 'B' for sometime and was later posted to Police Headquarters as Assistant Commissioner of Police. On March 16th, 1958, E.R.T. Madjitey was appointed Deputy Commissioner of Police.

On 9th October 1958, E.R.T. Madjitey was appointed Commissioner of Police (the rank of Inspector-General of Police had previously reverted to Commissioner of Police) thus becoming not only the first Ghanaian but also the first African South of the Sahara and in the whole of the British Commonwealth to command a Police Force. He served in this capacity from 1958 to 1964 when [and as he indicated in the script of a book he once contemplated writing] due to an attempt on the life of the President of Ghana Kwame Nkrumah by Constable Sam Ametewe, 

"I served as Head of the Ghana Police Force [Commissioner of Police] from 1958 to 1964 when following my opposition to Nkrumahs plan for disintegrating the Police Service under the guise of reorganization and my blunt refusal to be privy to the fabrication of evidence against Tawiah Adamafio, Ako Adjei and Cofie Crabbe, Nkrumah removed me and seven other senior officers from office, when a constable made an attempt on his life in circumstances which should have been obvious to the meanest sense that the constable acted entirely on his own volition to avenge the wrong done to him by Nkrumah through the unlawful detention and persecution of three of his close relatives."

E.R.T. Madjitey and the 6 top most in the Police Administration were removed from office [for reasons not established till today] and subsequently put in detention under the C.P.P. governments Preventive Detention Act.

During this illustrious career, E.R.T. Madjitey received many medals and citations also serving in many honorable positions. In recognition of his professional excellence and exceptional devotion to duty, Her Majesty Queen Elizabeth of Great Britain conferred a Baronage - CBE (Commander of the Most Excellent Order of The British Empire) on him in 1960.  

E.R.T. Madjitey was also awarded the Congo medal (for successfully heading United Nations Peace keeping missions during the the crisis in the Congo), Queens medal for meritorious duty, the Republican medal, Freedom key to the City of Grand Rapids, Michigan to mention a few. He was also a member of the International Association of Chiefs of Police
