Aston Villa's home Europa League clash against BSC Young Boys was temporarily halted as away fans clashed with police at Villa Park.
Objects were thrown towards forward Donyell Malen, the scorer of Villa's first goal, with Morgan Rogers also appearing to be hit.
The unrest continued following Villa's second goal, with more items being thrown at Malen.
Young Boys captain Loris Benito went over to supporters to try and calm the situation, but the unrest heightened as fans collided with police officers at the scene, with punches and seats being thrown.
Some of the fans were ejected as the game resumed several minutes after the second goal had been scored.
