Tamim Ahmed Chowdhury (Bengali: তামিম আহমেদ চৌধুরী; 25 July 1986 – 27 August 2016), known by his kunya Abu Dujanah al-Bengali (Bengali: আবু দুজানাহ আল-বাঙালি), was a Bangladeshi-Canadian Islamist militant that was the head of military and covert operations of the Islamic State's Bengal Province.^[1] For a while, he was alleged to be the emir of the Islamic State's Bengal Province, Shaykh Abu Ibrahim al-Hanif. He was the alleged mastermind of the July 2016 Dhaka attack at the Holey Artisan Bakery, which resulted in 29 deaths. He was killed in a raid on an IS safehouse in Dhaka by Bangladeshi forces on 27 August 2016.^[2]

He was born on 25 July 1986 in Sylhet, Bangladesh. Chowdhury was formerly a resident of Windsor, Ontario, Canada.

He attended J.L. Forster Secondary School in Windsor. He competed for the school in a variety of track and field activities in 2004. He graduated from the University of Windsor in Spring 2011, with an honours degree in chemistry.^[3]

Amarnath Amarasingam, Post-Doctoral Fellow with the Resilience Research Centre at Dalhousie University, said of Chowdhury's time in Windsor, "There were a few [people] who knew him from the mosque and from the social circles" and "He was a shy, skinny kid."^[4]

The Windsor Islamic Association (WIA) commented, "We can confirm that Tamim Chowdhury was from Windsor, though he was not a well-known individual in the community," WIA spokesperson Lina Chaker said.^{[5][6][7][8][9]}

He may have travelled to Syria at some point in 2012–13. He returned to Bangladesh sometime afterwards.^[10]

He was described as the "prime architect" and "one of the masterminds" of the July 2016 Dhaka attack.^[11][12]

On 2 August 2016, it was reported that the Bangladeshi police had offered a reward of 200,000 Bangladeshi taka ($2,500) for information leading to his capture.^[13]

Three militants, including Chowdhury, were killed during a joint forces raid at a house in Narayanganj Sadar Upazila on 27 August 2016. Monirul Islam, chief of Dhaka Metropolitan Police counter-terrorism unit, confirmed his death in an announcement reported in the Bangladeshi newspaper.^[14][15]
