SHENZHEN - South China police have arrested three Chinese people for the murder of a British citizen in the city of Shenzhen last month.

Hilary St John Bower, 60, was killed by his girlfriend surnamed Xu and two men on March 22, according to a statement from the Nanshan branch of the public security bureau of Shenzhen.

The suspects were caught a week ago. The police suspect the attack was caused by relationship problems between Xu, 38, and the victim.

Xu lives in Nanshan. One of her accomplices, surnamed Sun, is 28 and the other, surnamed Liu, is 23. The three all hail from Xianning city in Central China.

The police refused to disclose any more details, saying they are still investigating the case.
