A 63-year-old grandfather who was tasered by police after he refused to give his name has spoken to ITV News to explain his actions.

Judah Adunbi has told ITV News he refused to give his name to officers - because this was the second time he had been mistaken for a Bristol drug dealer.

Saturday's incident:

Since ITV News West Country broke the story yesterday, there has been online criticism of Mr Adunbi for not telling the officers his name.

He maintains he was right not to do so.
