Andheri police arrested three watchmen from Fatehpur, Uttar Pradesh, on Monday, for the murder of a senior citizen and his wife in Andheri (East) last week.
An eight-year-old child in Fatehpur identified the photos of the prime accused and received a reward of Rs 15. The accused have been identified as Amit Kumar, 18, Sikander Balmiki, 22, and Sudhir Balmiki alias Goolu, 20.
"Amit called Sikander and Sudhir on the pretext of watching television at Chandnani's house. They threw a bedsheet over the old lady and suffocated her to death. Then they pressed pillows over her bedridden husband's face, smothering him to death," said Archana Tyagi, additional commissioner of police, western region.
