A decorator denied in District Court yesterday that he fired ball bearings from an air pressure gun at five flats in Yuen Long over the course of two days, breaking the windows and hitting a passer-by. The court heard that Choy Sim-kit, 48, was found in a parked van with a pair of binoculars trained on one of the two buildings that had been targeted when he was arrested on March 31 last year. More than 300 ball bearings were also found. Choy pleaded not guilty to six counts of criminal damage, one of common assault and one of possessing a firearm without a licence. Prosecutor George Chu Fung-chee said: "Choy was arrested in a location which was within the firing range of the two buildings." Choy had been in a dispute with the owner of one of the targeted flats over a HK$30,000 bill for decoration work, police said. Chu told the court residents of Pearl House and Chun Chu Lau reported their flats had been shot at and the windows broken on March 30 and 31 last year. A passer-by was also hit but was unhurt. Police later found Choy inside a van, parked within yards of both buildings, looking through a pair of binoculars at Pearl House. The trial continues before Judge Anthony Kwok Kai-on today.
