Seven policemen involved in opening fire on locals in Tangail, who were protesting assault of a woman and her son Friday, have been closed to Dhaka Range, a top official said.

"We have already closed seven of the policemen who were involved in yesterday's firing incident. Rest of them will also be closed for the sake of a fair investigation," Deputy Inspector General (Dhaka Range) SM Mahfuzul Haque Nuruzzaman today told The Daily Star.

"The seven policemen include three sub-inspectors and four constables," he added.

Earlier yesterday, two probe bodies were formed to investigate the incident – one under the police and the other under the district administration.

At least three people were shot dead in Kalihati last afternoon as police opened fire during a clash with locals.
