A 29-year-old British man has been arrested on suspicion of murder after the deaths of two women in Hong Kong.
Police found the victims in an apartment block in the Wan Chai district after a call from the man at 3am (7.42pm GMT) on Saturday.
One woman, aged 25 to 30, had stab wounds to her neck and buttock and was pronounced dead at the scene, the BBC reported.
The body of a second woman, who had neck injuries, was found inside a suitcase on the balcony.
Hong Kong Police said they had detained the man and retrieved a knife from the apartment, in the J Residence block.
Assistant district commander Wan Siu-hung told reporters the woman whose body was in the suitcase had been dead "for quite some time".
The South China Morning Post reported that the man worked for a "top-tier global bank" and that the two women, of Asian or South East Asian origin, were believed to be "sex workers".
A resident of the 40-storey block, who said his fellow occupants were mainly expats, told the newspaper: "It was a shock because you would never expect something like this to happen in Hong Kong."
A spokesperson for the UK Foreign Office 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."
Post-mortem examinations are being conducted to determine the causes of the women's deaths.
