Two people have been arrested in the shooting death of rapper Slim 400, months after he was gunned down while sitting in a driveway … TMZ has learned.

Law enforcement sources say they arrested a man and a woman Thursday in connection to the December murder, we don’t yet know their identities or if they knew Slim 400 personally. We’re told the arrests were the result of a search warrant that will be sent to the D.A.

You’ll remember, the entire thing was captured on a Ring cam in Inglewood … you see a suspect walk up a driveway before confronting Slim and firing a series of shots. Slim attempts to go after the suspect, but collapses.

Shortly after the attack, he was taken to a local hospital where he was pronounced dead.
