Found a newspaper report mentioning it. It's not the one I was thinking of, which had a fuller description of events from Mr Adunbi, but it will do for now. You'd think that Mr Adunbi and McCalla (man wanted for GBH) lived next door to each other, from the number of times Mr Adunbi gets mistaken for him.

A race relations adviser tasered in the face by an officer has been mistaken by police again for the same wanted man.
Police stopped Judah Adunbi on 17 October because they mistook him for Royston McCalla who is suspected of a grievous bodily harm (GBH) offence.
PC Claire Boddie was cleared of assaulting Mr Adunbi with a taser after also mistaking him for Mr McCalla.
Black rights campaigner Desmond Brown, said the only similarity between the two was "they are both black men".
Avon and Somerset Police confirmed officers looking for Mr McCalla had stopped Mr Adunbi.
A spokesman said: "Officers on patrol in a marked car drove alongside a man in Chelsea Road to ask for his name, as they thought he might be a man wanted for a grievous bodily harm offence committed in Filton Avenue, Bristol, in the early hours of 11 October.
"The man was asked to confirm his name but he didn't reply.
"On closer look, officers were able to establish the man wasn't the wanted suspect and they drove off. We fully accept the man the officers spoke to wasn't the man we're trying to trace."
Mr Brown, said it was "amazing" Mr Adunbi had been stopped again yards from his house when he "looks nothing like" wanted man Mr Mccalla."Not the same height, build, type of dread locks or even eye colour," he said.
"The similarity, they are both black men," he said.
He said Mr Adunbi said the officers involved had been "laughing" despite the "distress caused".
