A marine police constable beat his girlfriend to stop her becoming a police officer because he could not bear the idea of her with boyish looks if she cut her hair short, a court heard yesterday. Ho Mei-shan, 21, who graduated from the police college two months ago and is now attached to Wan Chai police station, yesterday told the District Court that Lau Chun-tat, 21, had assaulted her after she told him she had applied to join the police in May last year. She said Lau had told her that he was unable to accept her short hair and had even bought her a wig. Ms Ho said she was attacked by Lau at his home in Wong Tai Sin on May 12 and suffered a broken nose. She claimed Lau threatened to kill her with a knife after she told him she had applied to join the force. Ms Ho said Lau had repeated the act and the threat at her home on August 10 and demanded she withdraw her application. The couple broke up after the incident but Ms Ho said Lau attacked her again on September 28 at a funeral. Ms Ho said Lau put his hands around her neck and squeezed, threatening to kill her. 'That was because I turned down his reconciliation request,' she said. Lau, after pleading not guilty to six charges of criminal intimidation, common assault, inflicting grievous bodily harm and assault occasioning actual bodily harm, through his defence barrister Ian Polson, presented a different story. In cross-examination, Mr Polson suggested Ms Ho had decided to join the force because she was unhappy with Lau for remaining in contact with his former girlfriend who was a police trainee. Mr Polson suggested Ms Ho had demanded that Lau leave the police to maintain their relationship. He alleged Ms Ho had told Lau that she had joined the force to keep an eye on him and his former girlfriend. Ms Ho denied the accusation. The court heard that she demanded Lau visit her home at 7am on May 12 because she did not want Lau to attend his former girlfriend's passing out ceremony that day. Ms Ho admitted they had breakfast together that day. The court heard Lau bought Ms Ho a long wig because she was sad to have short, boyish hair while the former girlfriend had long, beautiful hair. Ms Ho denied she had complained to Lau that he treated his former girlfriend better than her and that she had torn pages mentioning the woman from Lau's diary. The hearing before Judge Susana D'Almada Remedios continues today.
