Man Arrested Over Missing York Chef
A man from the York area has been arrested on suspicion of murdering missing chef Claudia Lawrence.
The man is aged in his 50s, North Yorkshire Police said.
A police spokesman said searches are being carried out in relation to the York University chef's disappearance and are expected to continue for a number of days.
He said Miss Lawrence, who was 35 when she went missing in March 2009, had not been found.
Miss Lawrence's family have been told about the arrest and are being supported by trained officers, police said.
Detective Superintendent Dai Malyn, of North Yorkshire Police, urged people not to identify the arrested man.
He said: ``To ensure the investigation and legal process are not compromised or potentially damaged in any way during this critical phase in seeking the truth about Claudia's disappearance, North Yorkshire Police strongly advises the media and members of the public against identifying the man who has been arrested.
``This includes naming or publishing images of the man on traditional media platforms or social networking sites.
``I urge everyone to show restraint and patience while we carry out these very important inquiries.''
A 35-year-old man who attacked a woman police officer with an axe, leaving her with a fractured skull and a finger hanging off, has been cleared of attempted murder.
The families of four teenagers involved in a crash caused by the dangerous driving of Thomas McMeekin have said they are "disappointed'' with his seven-and-a-half-year jail sentence.
