Rapper Tyler the Creator was arrested in Hollywood a few hours ago after he allegedly trashed some sound equipment inside the world famous Roxy on Sunset Blvd ... TMZ has learned.

The 20-year-old MTV award winner had performed at the venue earlier in the evening. The video below 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.

6:20 AM -- The West Hollywood Sheriff's Dept. tells TMZ ... security staff had contacted deputies last 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."

Cops called for backup and closed down Sunset Blvd for 30 minutes to regain control of the situation. Eventually the crowd dispersed and no one was injured.
