A POLICE constable gave two schoolgirls money for a taxi to get home after indecently assaulting them in his flat in police married quarters, a court heard yesterday. The girls, aged 14 and 15 and students at the same secondary school, were allegedly assaulted in separate incidents three months apart. On two separate occasions, Ng Ying-wai, 23, from the Castle Peak police station, asked the schoolgirls to give him a massage at his home in Tai Nam Chung Police Married Quarters, Castle Peak, Tuen Mun, the court heard. But instead, in each case, he ended up massaging the girl and indecently assaulting her, prosecutor Tracy Chan told Tuen Mun Court. At the end of each incident, Ng offered the girl concerned money to take a taxi home, Ms Chan said. Ng originally faced two charges of indecent assault and one of common assault. In December he was alleged to have sexually attacked the 15-year-old girl in his first-floor flat. On March 26, he allegedly sexually assaulted the other girl, who was then 14, and attacked her teenage male friend in Wu Tsui Road near the Tuen Mun Pier. Yesterday, the Independent Commission Against Corruption (ICAC) charged him with a further count of sexual misconduct. It was alleged the 14-year-old girl had been assaulted twice on the same day, the additional attack taking place on a staircase of the police quarters. Ng denied all the charges. The court was told the case was reported to the ICAC by a school social worker at the end of March and Ng was interviewed on April 19. It is now being handled by both the anti-corruption body and the police. Toby Jenkyn-Jones, defending Ng, said that the charges laid by the ICAC were unlawful and out of the body's jurisdiction. But magistrate Poon Chin-chiu overruled the defence application, after hearing that the ICAC had been authorised by the Attorney-General to handle the case. The ICAC had initially received a complaint of a breach of the Prevention of Bribery Ordinance, the court heard. The sexual allegations only arose during the investigation into alleged soliciting of advantages. Mr Jenkyn-Jones also asked that the cases be dealt with separately, saying the alleged incidents were not related. A joint trial was unfair to his client, he said. But Ms Chan insisted the case was a series of sexual offences with similar characteristics. The hearing continues.
