New Delhi: In a freak incident, a pair of three-year-old twins drowned in a washing machine at their home after their mother left them playing as she stepped out briefly to purchase washing power from a nearby shop on Saturday, police said.

Police said the tragedy was reported at 12.30 p.m at upscale Avantika Apartment in sector-1 Rohini. Rakhi, alone at home, was making preparations to wash clothes while her sons Naksh and Neeshu were playing around her.
