MUMBAI, Dec. 10 -- A jeweller was brutally attacked and robbed by two unidentified men at his shop in Vasai East on Tuesday afternoon, leaving him critically injured. According to the police, the incident occurred around 12.30pm at Ambika Jewellers in Waliv, when the store owner, Kalu Singh, was alone in the shop. Singh was arranging gold jewellery in the showcase when two masked men entered the store and stabbed him with a knife. They then fled with whatever jewellery they could lay their hands on. When Singh walked out of the shop covered in blood, passersby rushed him to Platinum Hospital in an autorickshaw since no ambulance was available. "We were shocked and the first thing we did was rush him to the hospital," said a local resident Yusuf Khan. The police have registered a case for attempted murder, robbery and launched a manhunt. The police have also begun nakabandis and are scanning CCTV footage to identify the assailants. "The jeweller is in a critical condition at the moment. We will record his statement when he is in a stable condition," a Waliv police officer said....
