Narayanganj city that has been in discussions across the country in connection with the sensational seven murders is now found to be an abode of dreaded militants too.
One of the top leaders of JMB, Salahudin, who  was snatched by his followers from a prison van at Trishal in Mymensingh, operation commander Ibrahim alias Khairul Bashar of Harkatul Jihad Al Islami (HuJi) and Sajid alias Masud Rana of JMB- all said to be  permanent residents of Narayanganj.
HuJi's Rafiq and Umar were also arrested this month also from Narayanganj.
The river port city, Narayanganj, has already been labelled as a metropolitan city with loose law and order and a drugs den.
Elites of the city are blaming the police and detectives for the rise of extremists in the city.
Detective police of Dhaka carried out many operations in the river port city over the few months but the police administration of Narayanganj is not that much active, sources alleged.  
On October 25 and November 1, chief of HuJi along with seven bomb experts was arrested by detectivepolice of Dhaka. Two laboratories for making high explosive bombs were found in Baktabali area of Fatullah in Naraynganj.
Arrested Commander Khairul Bashar of HuJi was trained in Pakistan and he operated extremist activities from the port area. Not only bomb blasts, he is, according to sources, also involved in forming an Islamist extremist alliance named 'Bangladesh Jihadi Group'.
The alliance consists of members from the extremist outfits Hijbut Tahrir, Hijbut Tawhid, JMB and Allah'r Dal, the sources said.
