A British man has been arrested over a double murder in Hong Kong.

Police in the former UK colony said a 29-year-old man was held after the bodies of two women were found at an address in the Wan Chai district.

One of the women - aged between 25 and 30 - was found with wounds to her neck and buttock, and pronounced dead at the scene.

The body of the other victim was found inside a suitcase on the balcony and she had sustained neck injuries, police said.

A Foreign Office spokeswoman said: "We can confirm that a British national has been arrested in Hong Kong.

"We are in touch with the local police and stand ready to provide consular assistance."

Officers were called to the address - reportedly an apartment - in the early hours and later seized a knife.

A statement from Hong Kong Police said: "Police are investigating a murder case in Wan Chai in the small hours of today (November 1) in which a foreign woman aged between 25 and 30, and another woman were killed.
