“ALEX PRETTI
NEW VIDEO OF CLASH WITH FEDS DAYS BEFORE DEATH”
SNIP
“The clip starts with Pretti yelling and appearing to spit on the vehicle as federal officers are driving away from the area ... before he brings his foot up and kicks and shatters the rear right tail light, leaving it hanging by cords.

Agents jump out of the SUV and chase Pretti down ... slamming him to the ground while a crowd gathers around them and screams at the agents.”

Inexplicably, after the tense altercation ends and Pretti's able to get back to his feet, agents just let him go ... leaving him on the street corner despite the damage he's done to the vehicle.

A rep for the Pretti family tells TMZ ... they knew about the incident on January 13. The rep says Alex sustained injuries but did not get medical care.”
