Gazipur: A case was filed over Monday’s crude bomb attacks on a prison van carrying Mufti Hannan, chief of the banned militant outfit Harkat-ul-Jihad al-Islami (Huji), and some of his associates at Tongi.

Firoz Talukder, officer-in-charge of Tongi Model Police Station, said police on Monday night filed the case under the anti-terrorism act against Mostafa Kamal, held after the attack and around five others.

Two crude bombs were hurled at the prison van carrying Mufti Hannan around 5:30pm on Monday while Mufti Hannan and his aides were being taken to Kashimpur jail from a Dhaka court.

Later, police arrested Mostafa, 22, hailing from Pagli village in Tarakanda upazila of Mymensingh, from the spot along with a bag containing two patrol bombs, two sound grenades, two crude bombs and two machetes.

The arrested youth reportedly confessed to police that he exploded the bombs targeting the prison van in exchange for Tk 10,000.
