Police shot de Menezes repeatedly on July 22, 2015 as he tried to board a subway train at Stockwell on his way to work, after they mistook him for a terrorist as he lived at the same building address as two bombing suspects.

LONDON — Relatives of a Brazilian man shot by British police who mistook him for a suicide bomber in the tense aftermath of the London subway bombings on Wednesday remembered 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, 27, who was shot repeatedly in the head in front of commuters as he tried to board a subway train to work. Police pursuing the electrician wrongly thought he was a suspect involved in a failed bomb attack which took place the previous day because he lived at the same address as two of the suspects.

The incident came two weeks after four suicide bombers attacked the London public transport system, killing 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.

On Wednesday relatives and supporters held a minute's silence at the moment de Menezes was shot. A short service was held outside the south London subway station where the killing took place, and flowers were laid at the foot of a mural marking his death.

De Menezes' family has brought the case to the European Court of Human Rights in Strasbourg, France, which hasn't yet made a decision. In June, a British government lawyer argued in court that the officers who killed the victim bore no personal responsibility for his death.

De Menezes' cousin, Vivian Figueiredo, said she was hopeful the family would see justice.

"I think we deserve it and a lot of people who are out there fighting for justice as well need this," she told the BBC.
