LVMPD Arrests Keefe D for the Murder of Tupac Shakur

Tupac Shakur's murder suspect went out for his morning walk, and then suddenly found himself in handcuffs ... charged in the nearly 30-year-old unsolved case.

TMZ just obtained police body cam footage from Duane "Keefe D" Davis' arrest, and you see him walking down a residential street when cops pull up, and tell him he's being busted.

Keefe D is totally compliant throughout the interaction with Las Vegas cops ... he doesn't resist at all. In fact, his only complaint was that he was "thirsty as f***" for the bottled water he was carrying.
