A MAN gave himself up after five years on the run in China following a knife attack on a friend, it was alleged in the District Court yesterday. Tong Bing-lau, 57, pleaded not guilty to wounding with intent. It was claimed Tong, with a group of men, attacked Chu Chun-ming, 36, a green grocer, at Wing Lee Mahjong School in Shamshuipo, on June 13, 1990. Prosecutor Peter Cosgrove told the court Mr Chu was severely injured in the attack and was taken to Caritas Medical Centre. The victim told Judge Sweeney half of his right middle finger had been amputated, he had scarring on his limbs and chin and injuries to his arm had left him disabled. 'Even now I still need to go to see doctors and I cannot use my hand as before,' Mr Chu told the court. He said he had to give up his job as a cook because he could not use his hand properly. The judge asked Mr Chu to come closer so he could inspect his scars. 'You are lucky to have survived the attack,' Judge Sweeney told him. It was alleged that Mr Chu had told a Thai prostitute not to repay a large sum in accrued interest on a loan she had taken out with the defendant, which led to the attack. Mr Cosgrove told the court the victim was discharged from hospital on July 9, 1990, and was re-admitted on July 23 for an operation. He was discharged again on August 1. The court heard Tong returned from the mainland and surrendered at the Shamshuipo police station on February 4 this year. The trial continues before Judge Sweeney.
