Mumbai, Nov. 19 -- Three masked men barged into a house in Vasai on Tuesday afternoon, tied up a woman and her son at knifepoint, and stole jewellery and cash worth Rs.10 lakh before fleeing. The Waliv police said that they have registered a case of robbery and four police teams along with a separate team from the crime branch are trying to track down the accused. The police said 48-year-old Sangita Raut's teenage son answered the door to find the three masked men. The accused allegedly pushed the 15-year-old aside, barged into the house and tied up the duo, injuring the woman in the scuffle that ensued. The trio then broke into Raut's cupboard and fled with jewellery and cash. Neighbours who heard the mother and son's screams rushed into the house to find the duo tied up. The police said that they were then rushed to the Platinum hospital in Vasai East where the woman is being treated for her injuries. The incident, which occurred in broad daylight, has created a stir among local residents. Purnima Chougule-Shringi, deputy commissioner of police, Zone 2, said, "We suspect the involvement of an insider who knew where the keys to the cupboard were kept and that there was jewellery worth Rs.10 lakh in it."...
