More than 600 objects linked to the British royal family, the former empire and Commonwealth have been stolen from a Bristol Museum storage facility, Avon and Somerset Police confirmed, releasing images of four people they want to speak to in connection with the break-in.

Investigators say the theft took place in the early hours of 25 September, when intruders entered the museum’s off-site collections store. Officers did not explain why the public appeal has come more than two months later but said they are seeking information about four individuals reportedly seen near the scene.

According to Bristol City Council, the missing items include medals, badges, pins, jewellery, carved ivory artworks, silverware, bronze figures and a range of geological samples. Philip Walker, the council’s head of culture and creative industries, said the collection chronicles nearly two centuries of Britain’s ties with territories across the empire and Commonwealth, offering “unique insights into lives shaped by imperial expansion and its aftermath.”

Detective Constable Dan Burgan, who is leading the inquiry, called the raid “a major loss for the city,” noting that many of the items were donations intended to support public understanding of a complex period in British history. “With the public’s help, we aim to identify those responsible and recover the objects,” he added.

Bristol’s own history is deeply entwined with the Atlantic slave trade; before Britain outlawed the trade in 1807, ships from the city forcibly transported hundreds of thousands of Africans to the Americas. The museum’s wider holdings—spanning Pacific Island artefacts, African textiles, photographs, films, personal papers and audio recordings—document that contested past and the people it affected.

Police urged anyone who recognises the four people in the images, or who may have been in the area on 25 September and seen suspicious activity, to come forward. The museum has begun cataloguing losses and reviewing security while working with insurers and heritage crime specialists to aid the recovery effort.
