From October 2007, he was appointed SP, Narail, where he served till 2009. He was promoted to DCP (Security) in DMP in the rank of AIG in 2009. Promoted to DIG, Mymensingh Range, from 2011 to 2013, as DIG, Dhaka Range, from 2013 to 2015, and as ADG in the RAB from 2015 to 2018. Thereafter, he was Addl.

Al-Mamun was appointed IGP on 22 September 2022 and assumed his position on 30 September.[9] He was scheduled to retire on 11 January 2023, as he would reach the age limit for governmental service.[10] But he was appointed on a contractual basis for a period of one and a half years from 12 January 2023 to 11 July 2024.[11] On 5 July 2024, his tenure was extended again, up to 11 July 2025.[10] In the aftermath of the non-cooperation movement and the overthrow of Sheikh Hasina, his contract was cancelled on 6 August 2024, and Md. Mainul Islam was appointed the new IGP.[12]

U.S. sanctions

On 10 December 2021, the U.S. Department of the Treasury added Al-Mamun to its Specially Designated Nationals (SDN) list over the killing of Ekramul Haque under the Global Magnitsky Act.[13][14][15] Individuals on the list have their assets blocked, and U.S. persons are generally prohibited from dealing with them.[16][17]

Shahidul Haque, was arrested from the Uttara area of Dhaka.[18] They are both facing multiple cases, including murder cases.[19] On 17 September, he was arrested in six more murder cases filed with Uttara East and West police stations.[20]

Al-Mamun's trial began on 20 November 2024. Along with seven others, Al-Mamun was accused of crimes against humanity, genocide, and overseeing massacres during the response to the non-cooperation movement.[21] He pleaded guilty and became a state witness, providing testimony against former prime minister Sheikh Hasina and Home Affairs minister Asaduzzaman Khan.[22] As a result of his plea, he avoided the death penalty and was sentenced to five years in prison.[23] He also apologized to the court and the country.[24]
