The incident took place in Mustafapur village two days ago when the accused Raktu Prasad hit his 19 year-old daughter with a sharp-edged object (used for cutting fodder) nearly 20 times after she resisted his bid to force himself on her while she was sleeping, Meenapur police station in-charge Madan Prasad Singh said.
The victim died on the spot, he said.
The accused, a farm labourer, was later arrested on murder charge (section 302 of the IPC) and sent to Khudi Ram Bose central jail in Muzaffarpur town, Singh said adding, the body has been sent for post-mortem.
The accused had thrown his son in-law out of his house in the middle of the night before committing the crime even as his four other children were fast asleep in another room.
