A man has been arrested on suspicion of the murder of a Chinese woman who disappeared six years ago.
A 37 year old man [A] was arrested on 7th June 2012 on suspicion of murder and taken to a central London police station, where he currently remains.
Acting DCI Manning said: "Although an arrest has been made we stress that all our appeals for information do still stand. Please come forward if you can assist.”
Lihau Cao, also known as Li or Lisa Ekaireb, was last seen at the end of October 2006 when she was four months pregnant.
Although she lived in London with her husband, she was not reported missing to police until February 2007 when her family in China became increasingly concerned as to her whereabouts.
Li, who left China in 2002, had been working as a waitress and dancer in Dublin until June 2006. She is then known to have moved with her husband to Hampstead NW3, and was thought to be working as a waitress or a dancer in the Chinatown area.
Following continued efforts to trace her, investigating officers now believe she was murdered after the last known contact with her family in October 2006.
Police are keen to piece together her final movements and are appealing for anyone with information to contact them.
Li was born in 1979, and was 27 years old when she went missing. She was 5ft 4 inches tall, of small build and had long shoulder length black hair.
