The prisoners, all convicted of theft and robbery, approached a security guard and told him that one of them was ill, Anand district Superintendent of Police B S Jebalia said.

When the guard opened the door, the prisoners snatched his rifle and hit him on the head with it before escaping, Jebalia said.

An alert had been sounded to nab the accused, he added.
