A young Delhi municipal councillor allegedly murdered her one-and-half-year-old daughter before committing suicide in her west Delhi residence early this morning, with her family alleging that she took the extreme step due to dowry harassment.

Satyam Yadav (26), Congress councillor from Nangloi East in North Delhi Municipal Corporation, was found hanging from the ceiling of her house while her daughter Vanishka was found murdered in her room, a senior police official said.
