They demanded the same also on the 'killings by Bangla Bhai'.

Standing on a point of order, AL lawmaker Suranjit Sengupta said Rab killed a central leader of Bangladesh Chhatra League in the name of crossfire in Chittagong on Monday while a few days ago, `Bangla Bhai' killed a Bangladesh Samajtantrik Dal leader in Rajshahi.

"If the so-called crossfire continues, no one knows when the ministers would be caught in the crossfire," Sengupta said.

Speaker Jamiruddin Sircar refused to accept the point saying law would take its own course.

Taking the floor, Mohammad Nasim said people in the country's northern region are in constant fear of violence unleashed by `Bangla Bhai' and his men.

Nasim, a former home minister, said people wonder what gives such strength to 'Bangla Bhai' that even the prime minister's directive to arrest him did not work. He demanded statement from the state minister for home affairs.

Hinting at Rab, Nasim said there could not be a 'self-declared terrorist force' in the country.

When State Minister for Home Affairs Lutfozzaman Babar attempted to say something in reply, some members of the treasury bench signalled him to let go of it.
