Detectives from Operation Tundra, along with officers from the Metropolitan Police, carried out two warrants at addresses in London this morning. The arrests were made in East London, with other addresses now also being searched. The van thought to be involved with the theft was stolen from the Tower Hamlets area, although the exact details of the location of the arrests are as yet unknown.

Both men are being currently transported to Cambridgeshire.

The news comes only hours after an appeal was made on the BBC's Crimewatch, which resulted in more than 10 calls, with further calls made to the police hotline set up specifically for the case.

Detective Chief Inspector McCrorie, who appeared in the appeal, said:

"There was a significant response to the appeal but it is going to take time to work through inquiries. We are still keen to hear from anyone who has information about the burglary or the four men we are keen to trace in connection to the theft.”
