A FIRE at a pork stall that damaged four frozen pig carcasses and a butcher's chopping table was lit deliberately, the District Court heard yesterday. Decorator Li Mun-tong, 37, and pork hawker Tsang Kin-fat, 33, both denied a joint count of arson. Prosecutor Robert Andrews said patrolling police officers discovered the fire on the first floor of Yeung Uk Road market, Tsuen Wan, just after 2 am on June 12 last year. The Crown alleged the fire caused $40,000 damage to Wong Yuet-ngor's pork stall, four pieces of pig carcass and an iron gate. The prosecution alleged Li and Tsang lit the fire because operator Ms Wong's brother, Wong Wai-chuen, owed Tsang money. The hearing before Judge Kilgour continues.
