A mainlander who claimed to have a bomb strapped to his body was arrested after he tried to force his way across the Huanggang border checkpoint into Hong Kong yesterday. A rumour had been spreading in Shenzhen that Hong Kong would offer residency to illegal immigrants today to celebrate the handover and the appointment of Chief Executive Donald Tsang Yam-kuen. The Hong Kong government strongly denied there would be any such amnesty. It is not clear if the rumour was related to the incident of the middle-aged man who was seen trying to sneak through the vehicle channels at 11.15am. He was stopped by mainland customs officials. He was holding a remote control device when he refused to show his identification document and claimed to have a bomb. Officials knocked him down, but found no bomb. The two vehicle channels were closed for an hour due to the incident.
