Following PSV's 1-0 Europa League loss to Arsenal on Thursday night, UEFA launched an investigation into the actions of their supporters.

In the Emirates Stadium, the Dutch fans tore out seats and threw flares in the direction of the home end.

The game's lone goal was scored in the 71st minute by Granit Xhaka.

The win, which is Arsenal’s fourth in the competition, means they have already secured a top-two finish in the group.

Mikel Arteta’s men can now confirm top spot with another three points in Eindhoven next week.

Footage captured by those inside the stadium showed one fan throwing a flare towards the home sections, fortunately missing the departing Arsenal fans.

Several were also seen ripping out seats, with riot police forced to intervene and UEFA launching an investigation.
