Relatives of a Brazilian man shot by British police who mistook him for a suspected suicide bomber in the tense aftermath of the London subway bombings are remembering his death 10 years ago.

Family and supporters are still trying to hold British police to account for the July 22, 2005 killing of Jean Charles de Menezes, who was shot dead in front of commuters as he tried to board a subway train. Police thought he was a suspected suicide bomber targeting the subway network, two weeks after bombers attacking London public transport killed 52 people.

The police force was fined 175,000 pounds ($274,000) in 2007 for violating health and safety rules, but no individual was charged.

A service was held in London Wednesday to mark the death.
