He was reacting after a banger thrown from the stands landed near him
A Swedish football match between top flight clubs Malmo and IFK Goteborg was abandoned after a player threw a corner flag at opposition supporters.
A banger was thrown from one of the stands landed close to where Malmo substitute Tobias Sana was warming up, before exploding loudly.
Sana retaliated by pulling the corner flag out of its base and throwing it towards the stand:
