Detectives investigating the theft of valuable Chinese works of art from the Fitzwilliam Museum in Cambridge are appealing for information about a vehicle believed to have been used in the burglary.
They've identified a white VW caddy van which they think the gang got away in.
The van has a dent in the driver's side panel and tinted windows to the rear. It is believed to have been stolen in the Tower Hamlets area of London on April 7.
Detective Chief Superintendent Karen Daber, who is overseeing the investigation said: "We know the van we are interested in tracing travelled down Trumpington Street, away from the Fitzwilliam Museum at about 7.40pm on Friday April 13.
"The vehicle has been seen on CCTV going past the Trumpintgon Street Park and Ride and heading in the direction of the M11.
"We are also keen to know where that van is now and anyone who has seen it since April 13 should contact us immediately."
Anyone with information should contact police on 101 or Crimestoppers, anonymously, on 0800 555111.
