"Star Trek" star Avery Brooks was busted for DUI ... TMZ has learned.
63-year-old Brooks -- who played Benjamin Sisko on "Star Trek: Deep Space Nine" -- was arrested Sunday in Wilton, Connecticut after someone complained he was driving erratically.
Cops pulled Brooks over and after a sobriety test he was arrested for DUI.
If convicted, Brooks could get 6 months in the pokey, although in most states first-time offenders end up with probation -- and as far as we know Brooks has no priors.
A rep for Brooks has no comment.
