Brian Worth obituary

My grandfather Brian Worth, who has died aged 84, was deputy assistant commissioner of the Metropolitan Police and head of CID operations at Scotland Yard - at the time the youngest man to have reached that rank. In his CID role he led the investigation into the Brink's-Mat robbery in 1983 and in earlier years was part of the team investigating the Rolls Razor fraud case in 1968.

In charge of all the detectives in London, he was also responsible for creating the Met's kidnapping protocol and was a liaison officer for Interpol and the FBI, flying to the US a number of times throughout his career.
