The grandson of the former London gangland enforcer "Mad" Frankie Fraser is wanted over an alleged drug-smuggling plot, police have said.
Anthony Fraser, 39, is believed to be hiding on the Costa del Sol in Spain.
Originally from London, he went on the run after two tonnes of cannabis was found hidden in a lorry in 2009.
He is one of 10 suspected criminals whose details will be released later on Monday by Crimestoppers in the Spanish city of Alicante.
The Serious Organised Crime Agency and Spanish police are also involved in the announcement, codenamed Operation Captura.
They hope to track down the 10, all of whom are thought to be based in southern Spain.
Others on the list are understood to be suspected of murder, child sex offences, kidnapping and robbery.
Fraser disappeared after cannabis with a street value of £5m was discovered at a storage unit in Grays, Essex, in a truck full of frozen chicken from the Netherlands.
Five people were subsequently convicted of drugs offences and jailed for between six and seven years at Southwark Crown Court.
A second suspect, Neil Mulligan, 39, is waiting to be tried in the UK after his arrest in Spain in December.
Fraser's grandfather, 87-year-old "Mad" Frankie Fraser, was an associate of the notorious Kray and Richardson crime families.
