A British man has been arrested in Hong Kong after the bodies of two women were found at an apartment, including one inside a suitcase.

The other woman, aged between 25 and 30, is thought to have had her throat cut.

She had wounds to her neck and buttock and was found unconscious by police officers. She was later pronounced dead at the scene.

Wan Chai District Assistant Commander Wan Siu-hung said: "We believe the death was caused by a sharp object which cut the throat of the deceased.

"This led to copious bleeding. When the police found her, she was lying in the living room. The room was messy."

The other woman also had neck injuries and was discovered in a suitcase on a balcony in the Wan Chai district.

She was bloated, wrapped in a blanket, and police estimate she could have been dead for some time, according to reports.

Officers were called to the address - reportedly an apartment - in the early hours on Saturday. A knife was seized inside the property and a small quantity of cocaine was also found.

Police in the former UK colony said a 29-year-old British man was arrested at the scene over the double murder.

A statement said: "Police are investigating a murder case in Wan Chai in which a foreign woman aged between 25 and 30, and another woman were killed.

"At about 3.42am, a 29-year-old foreign man made a report and requested police to investigate a case in a unit at 60 Johnston Road, Wan Chai.

"In the course of investigation, police found a suitcase at the balcony of the unit, and a female dead body with neck injuries was found inside the suitcase.
