A Pakistani man living in Hong Kong has been charged with murder in the slayings of three sex workers in the past week, police said Wednesday.

The 24-year-old man, whose name and profession were not released, was scheduled to appear in court later Wednesday, police spokesman Fai Chau said.

Police arrested the Pakistani man Tuesday after he returned to Hong Kong from the neighboring gambling enclave Macau. Officers said they seized mobile phones belonging to two of the victims from the suspect when he was arrested.

Four sex workers, aged 27 to 35, have been killed in Hong Kong since Saturday.

The suspect has been charged with murder in three of the slayings.

One woman was strangled with a shower hose, and the apartment where she had been found had been robbed, police said. Another body was found with a swollen forehead and injured jaw. Their bodies were found in apartments in the suburban New Territories and in a residential district on Hong Kong island on Saturday and Monday.

Police spokesman Chau said the investigation was continuing, and that no other arrests have been made.

The suspect faces life imprisonment if convicted.
