Legia hooligans clashed with stewards in the stands at the Polish Army Stadium during their Champions League game against Borussia Dortmund on Wednesday.
Trouble erupted in the first half of the match as a group of Legia hooligans attempted to storm the Dortmund end.
The troublemakers then attacked security staff with spray as they prevented them from entering the away end. There were no reports of injuries.
Five Legia hools were arrested after the incident.
