New Delhi: A 40-year-old woman allegedly strangulated her teenage daughter and then hanged herself in Kalwa area of the city on Friday, Thane Police said.

The suicide note purportedly written by the woman, Pradnya Parkar, said she was under extreme stress and hence she killed her daughter Shruti (17) and was going to kill herself.

The incident apparently took place between 8 and 9 this morning when her husband had gone to the gym.

On return, he found the door of the flat locked from inside. When it was broken open, the bodies of Pradnya and Shruti, who studied in Class 12, were found. Further probe is on.
