Detectives are today appealing for help in solving the mystery of a safe found dumped in the River Thames at Greenhithe.

Two men were seen throwing the heavy strongbox over the sea wall at Sara Crescent at about 8am on Saturday.

The safe - believed to have been stolen - was recovered later that day at Denton Wharf in Gravesend.

Police said it had been damaged and contained a set of digital scales and other objects too water-damaged to be identified.

A 22-year-old Sittingbourne man was arrested hours later on suspicion of theft and bailed pending further investigation until August 27.

DC Bill Looker said: "We have reason to believe this safe was stolen before it was dumped, but are looking for information to help us establish the circumstances around the theft and to try to help us locate its owner.

"I'd ask anybody with information to call me on 01474 366042. Alternatively, to remain anonymous, call Kent Crimestoppers on 0800 555111."
