The attackers also laid a seize to the Home but withdrew when police came.

Kawsar, a former resident of the Home had gone there to request the authorities to take back five students -- Dulal, Belal, Helal, Alam and Masud-- expelled from the Home for allegedly humiliating one of its female teachers, Laizu Razzak.

But its Assistant Director refused and called in Ansar members

This angered Kawsar, who started shouting and ransacking furniture and other things, police and officials at the Home said.

This drew locals who joined Kawsar.

Police arrested Kawsar. A case has been filed against him, police said.
