Tyler the Creator Arrest Shuts Down Sunset Blvd

The 20-year-old MTV award winner had performed at the venue earlier in the evening. Video shows Tyler appearing to go off on the sound engineer inside the club (WARNING: video contains some obscenities).

We're told cops were called by Roxy staff around 11:30 PM ... and Tyler was taken into custody in front of his mother ... who was visibly upset and yelled at the cops.

Tyler was arrested on suspicion of vandalism and was taken to a nearby station to be booked.

Update The West Hollywood Sheriff's Dept. tells TMZ ... security staff had contacted deputies Thursday night to report Tyler had "just destroyed an electric soundboard belonging to the venue."

Cops say, "As [Tyler] was being escorted to a nearby radio car, the crowd exiting the venue became angry and rushed into the street, towards deputies."
