Tyler the Creator was arrested Saturday afternoon at an airport in Texas ... after cops say they had a warrant with his name on it -- for starting a riot at the SXSW festival.
Austin PD officials say Tyler was booked this afternoon for inciting a riot at his concert Thursday.
According to reports ... Tyler egged on hundreds of people at the gig -- telling them to break down the barricade to get in -- and it was a scary scene that pissed off management.
As you may recall, Tyler's Wednesday night concert was cancelled the night before -- after a driver plowed into a crowd of people waiting to get in -- leaving 2 dead and 23 injured.
Cops say Tyler "encouraged behavior causing an immediate danger and injury to persons."
Tyler's still in custody on a $3,500 bond.
