Driven by the constant harassment by her husband and in-laws for a male child, a woman allegedly drowned her three-month-old daughter in a water tank at her home in the Kalachowky area of central Mumbai, police said.

The incident took place at the Sangharsh Sadan building in the Ferbunder area of Kalachowky on November 30, an official said. The 36-year-old accused had initially claimed that the baby had been kidnapped by an unidentified woman who had come to the house and administered a sedative to her on Tuesday, an official said.
