A woman was found strangled and her three minor daughters thrown off the fourth floor of a building in Etawah district of Uttar Pradesh early on Tuesday, police said.
All four have died. The husband of the woman, an egg vendor, has been arrested in connection with the deaths and is being interrogated, a police officer said.
An officer said that the incident took place in Kanshiram Colony, where Chote Lal Jatav, 28, lived with his wife Neha, 25, and three daughters -- Tulsi, 7, Moni, 4, and Kallo, 2.
Neha assisted her husband in the egg cart business. The couple returned home around 10 p.m. on Monday and no one saw them thereafter, a neighbour told the police.
