Police have tasered a 63 year old race-relations worker after wrongly believing he was a wanted man.

Grandfather Judah Adunbi helped found an organisation to improve relations between Bristol's Black and Ethnic Minority groups and Avon and Somerset Police.

He was tasered by police after refusing to give his name when they confronted him - and asked him if he was someone else.

The footage, obtained exclusively by ITV News, shows the taser hit Mr Adunbi in the face:

I felt that was it. Because of the way I fell back. The way I fell backward on the back of my head. I was just paralysed. I thought that was it. I thought they were taking my life. Mr Adunbi

Mr Adunbi said he felt 'humiliated' at being mistaken for a wanted man. He said: "At first you don't accuse someone of being someone else. You ask questions. The first thing they should have done is come to me in a polite manner. The way they approached me - they were accusing me. That is wrong."

The Independent Police Complaints Commission in investigating the shooting, which happened in Easton on Saturday morning. Both officers remain at work.

Chief Superintendent Jon Reilly of Avon and Somerset Police told ITV News: "I understand the community are going to have concerns. And we'd really like to answer those. But as there's an ongoing investigation that's very difficult for us to do."

"I want to reassure the community the whole incident was captured on body-worn camera. Both officers were wearing it. And we're determined to understand what happened. That's why we've referred it, voluntarily, to the Independent Police Complaints Commission for them to assess whether an independent review is necessary. We work really hard to work positively with all communities and I see no reason why that should change."

Mr Adunbi said: "It's a little distasteful in my mouth. To know that one of the founder members of the Independent Advisory Group which was created some years ago in order to improve better relationship between the AfroCaribbean community and the constabulary and to be treated like this it's difficult."
