The front gate of a luxury house in Tai Po, home of a local businessman understood to act as an honorary consul for the West African country of Mali, was damaged when a stolen car was reversed into it before dawn yesterday. Policemen were called in after a security guard, 36, heard a loud bang and went to investigate and found the main gate damaged at about 5am. The guard told officers that as he came out to investigate, a dark-coloured car driven by a man left the scene at high speed. About 10 minutes later, a burning car suspected to be linked to the attack was discovered by patrolling officers on the Tolo Highway near Pak Shek Kok, Tai Po. After firemen doused the flames, police found a pair of car number plates in nearby bushes. Police said the car had been stolen in Shamshuipo on Sunday. The owner of the house is understood to be a local businessman and also the honorary consul of the Republic of Mali. 'Preliminary investigation showed that the man had not had a dispute with anyone and he had not received any warning or threatening call prior to the attack,' one of the investigators said. Detectives from Tai Po district crime squad are investigating the case. No one has been arrested.
