Exclusive: Retired NHS worker Nicholas Stone died after becoming unwell at protest against far-right Bristol Patriots

The daughter of a retired NHS worker is calling for a full and independent investigation into the death of her father after it emerged he died after police contact at a protest against the far right.

Nicholas Stone, 65, who lived in Bristol, died on 10 January after becoming unwell at a protest opposing the rightwing group Bristol Patriots, who were staging a demonstration in the city centre.

According to information from Stone’s family’s legal team and the police, during the demonstration, at approximately 11.54am, Stone ran towards Clare Street at the same time police officers were approaching that street to form a cordon. Two officers used force to prevent Stone passing.

As a result, he ended up on the ground on his back. He was helped back to his feet by several others attending the protest. At about 1pm, a first aider was asked to assist him, as he was siting on a bench and said he was feeling clammy and cold. She helped him get in a taxi at 1.19pm. Avon and Somerset police told the Guardian they received a call from the ambulance service about a man in cardiac arrest at 1.50pm. He died at the scene.
