Six persons were seriously injured when goons hurled crude bombs at the residence of a farmer near Raghunathganj in Murshidabad district on Tuesday night.

The attack took place hours after Helaluddin Sheikh, 58, raised protests when a group of drunken youths used abusive language in their chat on a road at Lakshmijola village.

"Shortly before midnight, the same group is suspected to have returned to the spot to hurl at least a dozen crude bombs at Helaluddin’s home. Helaluddin, his two daughters, younger brother and sister-in-law suffered injuries,” said a Raghunathganj police officer.

A civic volunteer, Minarul Haque, 30, who lives nearHelaluddin’s home, was injured as he was struck by a shrapnel when he stepped out on hearing the commotion.

Helaluddin, his daughters Mahmuda, 23, and Rumali,20, younger brother Kamaldar Sheikh, 44, sister-in- lawTanuja, 39, and Minarul were admitted to Jangipur subdivisional hospital. Tanuja was later shifted to Murshidabad Medical College as her condition deteriorated.

A police team has been posted outside Helaluddin’shome. Helaluddin registered a complaint with Raghunathganj police later on Wednesday, following which two persons — Saidur Rahman andHukumuddin Sheikh — were arrested.

District police superintendent Bholanath Pandey said the incident was being probed to find out the reason for the attack.
