Police are looking for a gang of South Asian muggers after the fourth robbery in six days in Kowloon. The latest case occurred early yesterday and involved a 24-year-old man who was attacked by two men in Woosung Street, Yau Ma Tai, and lost his iPhone. He sustained head injuries. The first incident happened early last Friday when a 26-year-old woman was struck on the head and robbed of her iPhone in Tung On Street, Yau Ma Tei. On Monday, a 15-year-old girl was robbed of a mobile phone and a PSP game console in an attack by five South Asian men in Hoi Fai Road, Mong Kok at about 5pm. Six hours later, a group of South Asians assaulted two men, aged 20 and 24, in Hung Hom Road and stole their mobile phones.
