British nigerian actor david ajala joins star trek cast

I'm not aware of any information that suggests British-Nigerian actor David Ajala has joined the cast of Star Trek. It's possible that you may be thinking of a different project or that this is a rumor or speculation.

However, David Ajala is a talented actor who has appeared in a number of TV shows and films, including "Fast & Furious 6", "The Dark Knight", and "Supergirl". He has also starred in the TV series "Nightflyers" and "Columbus".

If you could provide more context or clarify which Star Trek project you are referring to, I may be able to help you better.
