A man with assault rifles was arrested early Sunday after telling cops his destination was the Pride parade later today in West Hollywood ... law enforcement sources tell TMZ.
Our sources say Santa Monica PD responded to a prowler call and found the man nearby the house that was allegedly targeted.
We're told he informed cops he was on his way to meet a friend for the Pride parade 10 miles away in WeHo. At a point cops searched his car and our sources say they found multiple assault rifles with a number of loaded magazines that were stacked and taped together -- a marker for someone looking to fire multiple rounds in rapid succession. Cops reportedly also found explosives and camouflage gear.
We're told the man has been arrested.
Santa Monica PD will not comment.
We're told the FBI is now involved. We do not know if cops have a lead on the identity of the "friend" of the man arrested.
