Suspected bandits burned a family of 12 to death Thursday in central India in a revenge attack involving rival gangs, police said. The bandits attacked the family and beat them up before "locking them up in a thatched roof hut and then setting it on fire," said Brij Lal, a senior police officer in Uttar Pradesh state. The charred bodies of five men, four women and three children were recovered. Lal said the attackers apparently were avenging the killing of one of their own last week by the head of the family, Beta Singh Gaur. The attack occurred in the Chambal region, a rugged maze of ravines straddling the border between Uttar Pradesh and Madhya Pradesh. The region has long been a haven for bands of outlaws, known as dacoits. The attack occurred on the Madhya Pradesh side. Police believe the attackers escaped into Uttar Pradesh, Lal said.
