Arsonists attacked a new restaurant in Macau with a home-made bomb early yesterday. Judiciary Police are investigating the incident at the Look Ting Kei Seafood Restaurant which opened last week at 114 Estrada de Coelho de Amaral, near the landmark Kun Yum Temple. At about 5 am yesterday, a home-made petrol bomb was thrown at the main entrance of the restaurant, which was closed. The device exploded and fire blackened the shop's steel grille, but no other damage was reported. Police found another, unlit, petrol bomb - a beer bottle filled with petrol and stuffed with shredded cloth - at the shop's back door. A suspicious-looking paper box under a car parked near the restaurant was detonated by remote-controlled robot, and turned out to be empty. The restaurant owner, who was not named by police, said no threats had been received, nor had a protection fee been solicited before the attack. The investigation continued last night but no arrests had been made.
