No, that didn't happen. You're confusing two different events together.

The guy who posted the photo of brown skinned people with the "imagine the smell" comment was American and lost his job. The UK wasn't involved in any way. [0]

The comedian you might be thinking of is Graham Linehan - he was arrested for inciting violence against trans people and has a long string of twitter posts quoted as possible reasons. (and had a similar post with the comment of "a photo you can smell" but with a photo of a trans rights protest, so perhaps the origin of the confusion?).
