"Rare and irreplaceable” medals have been snatched by thieves who raided a Colchester museum.

Crooks targeted Hollytrees Museum on Tuesday night breaking into a display cabinet.

Three gold and two bronze pieces have been taken.

The exhibits, which all date from the second half of the 19th Century, had been on show since last May, and were last week repositioned.

The medals include those awarded to Paxmans at the Crystal Palace Electrical Exhibition, the Paris Exposition Universelle International, and Australian International Exhibition in Sydney.

The break-in happened at 8.30pm on March 1.

Darius Laws, the Colchester Council’s heritage boss, said the crooks had been caught on CCTV.

He said: “I am deeply shocked and saddened by the theft of these rare and irreplaceable objects from the museum’s collection, and appeal for their immediate and safe return.

“Fortunately, we have been able to share some useful CCTV of the incident and are continuing to assist the police with their ongoing investigation.

“This is not simply the theft of gold medals, but it is the theft of Colchester's heritage.

“I would appeal to those responsible to reconsider what they have done, do the right thing and return the medals so everyone in Colchester can enjoy them.
