Mumbai: A 54-year-old man allegedly stabbed three neighbours to death at a residential building in south Mumbai on Friday, police said.
Two others were injured in the attack and the condition of one of them was serious, they said. Earlier, a senior police official had put the death toll at four.
The grisly incident took place around 3.30 pm at Parvati Mansion on Grant Road, an official said, adding that the accused, identified as Chetan Gala, was soon arrested. His wife and children had left him two months ago, and he suspected that his neighbours had instigated them, the official said.
He had been mentally disturbed ever since, and on Friday, upon spotting his neighbours, he went to his house, picked up a knife and allegedly attacked five persons from neighbouring families. The injured were rushed to a private hospital in Girgaum and civic-run Nair hospital where Jayendra Mistry (77), his wife Ilaben Mistry (70) and Jenil Brahmbhatt (18) died during treatment, the official said.
