A man was stabbed in the chest yesterday in a robbery at his home. The raid is believed to have been carried out by three mainland illegal immigrants who escaped with $250,000 in cash and jewellery from a Kowloon Tong house last week. Yesterday, three robbers climbed into a fifth-floor apartment in Pilgrims Way, Beacon Hill, through an unlocked window on the balcony at about 5am. They took a knife from the kitchen before approaching the master bedroom, waking the 49-year-old man and his wife. Chief Inspector Ho Yuen-ha said the man was stabbed in the chest and then the couple were pushed into a bathroom. The robbers ransacked the premises and fled with $2,000 and a video camera. The couple hurled objects out of the bathroom window to alert police. The man was taken to Queen Elizabeth Hospital in stable condition. His wife, who suffered scratches to her right arm, was discharged.
