Night beat constables’ suspicion led to arrest of a mason, Venkataramana, who was fleeing after allegedly setting his second wife Shanti ablaze in Akula street in Rajampet town on Thursday night.

Venkataramana allegedly doused his wife in kerosene following family dispute, and was fleeing with his nine month-old son, when night beat constables intercepted him. When the mason gave different versions on the whereabouts of the child’s mother, the constables grew suspicious and escorted Venkataramana to his house, where they found his wife’s charred body, police said.
