Shaqiri was conducting post-match media duties on the pitch following his side's 2-0 win over Northern Ireland in World Cup qualifying in Geneva.

A man approached the former Liverpool player and put a coat around his shoulders that bore the symbol of the UCK, or Kosovo Liberation Army, a militia that fought for Kosovan independence from Yugoslavia and Serbia.

Shaqiri, who is of Kosovo-Albanian descent, promptly removed the garment and placed it out of sight of the camera before continuing his interview.

The incident caused uproar in Serbia, with newspaper Kurir describing it as a "scandalous scene" and calling on UEFA to act.

In a statement posted on Twitter on Sunday, the Swiss Football Association (SFV) said: "It is unacceptable that people want to use football stadia, and in this case a player's interview after a match, for political propaganda purposes.

"Xherdan Shaqiri reacted in an exemplary manner, stayed calm and did not react.

"The man was questioned by police and an immediate stadium ban was imposed on him."

Shaqiri and team-mate Granit Xhaka were fined 10,000 Swiss francs at the 2018 World Cup after celebrating goals in a 2-1 win over Serbia by making a double-headed eagle gesture.

FIFA considered the celebration, which symbolised the emblem on the Albanian flag, to be "unsporting behaviour".
