Armed police seized explosives, ammunition and a loaded gun when they stormed a hotel room in Tsim Sha Tsui East, the High Court heard yesterday. But the members of the Special Duties Unit assault team, who arrested two men inside the room at the Hotel Nikko in Mody Road, first had to deal with the problem of a stubborn door, the jury was told. Andy Li Wing-wah, one of the officers taking part in the raid, said the police first tried to open the door by using the room card. When this failed, a 22-kilogram battering ram was used but the door would still not budge. A constable then used his shotgun to fire three times at the lock. Even then, the door did not give way. Finally, the battering ram was used again and officers were able to charge into the room. Prosecutor Wayne Moultrie said the police arrested Chow Tak-shing, 26, who was sitting on the bed, and Lau Wai-keung, 27, who was hiding in a cupboard. Both men deny unlawful possession of a loaded semi-automatic pistol with four rounds of ammunition. They also pleaded not guilty to having five cylindrical blocks of explosives and tracer ammunition. Mr Moultrie said the police raid involved the Organised Crime and Triad Bureau and the Special Duties Unit. The gun was found under a bed and the ammunition and explosives in a bag on a table. The trial, before Mr Justice Mohammed Saied, continues today.
