Police investigating the disappearance of York chef Claudia Lawrence have arrested a 59-year-old man on suspicion of murder.
Lawrence (pictured), has not been seen since she failed to turn up for work at York University in March 2009, despite an extensive police search and huge publicity.
The chef, who was 35 at the time, had been seen the previous evening close to her home in the suburb of Heworth. Her father reported her missing the following day.
Forensic examinations were being conducted and were expected to continue for several days, according to a spokesman for North Yorkshire Police, who added that a car was seized and further arrests could not be ruled out.
The force launced a review of the case last year, led by Detective Superintendent Dai Malyn, and have carried out new forensic work and searches of Lawrence's home.
A fresh appeal for information, made on the fifth anniversary of Lawrence's disappearance in March, was broadcast on the BBC's Crimewatch programme, reported the BBC.
Police revealed several new lines of inquiry generated by the review of the case and fresh examination of her home, including fingerprints that had been uncovered using techniques not available in 2009.
A DNA profile of a man was also found on a cigarette end discovered in Lawrence's Vauxhall Corsa.
