A 36-year-old woman was beaten to death in Kanpur by men who were accused of molesting her minor daughter and were out on bail, a senior police officer said on Saturday.

The woman and her sister, who were witnesses in the 2018 molestation case, were assaulted by the accused and were admitted to hospitals here.

The woman died at Lala Lajpat Rai Hospital on Friday while her 26-year-old sister is battling for life at a private hospital in Chakeri.

Superintendent of police (Kanpur East) Raj Kumar Agarwal said: “Three persons have been arrested and raids are being conducted for the arrest of another elusive accused, Chand Babu. Two other accused were arrested on Saturday following a police encounter.”

The police had arrested all the four accused after registering a case under the IPC and the Protection of Children from Sexual Offences. But the accused had got bail.
