Champions League referee Slavko Vincic has been released after he was arrested as as part of a drugs and prostitution raid at a party in Bosnia and Herzegovina.

The Slovenian, who took charge of Manchester City's European clash with Shakhtar Donetsk in November, has spoken about the events after he was allowed to return home on Friday. 

The official attended what he claims was an invitation to a business lunch in the Bosnian city of Bijeljina but found himself caught up in the raid and was arrested along with Tijana Maksimovic, who police reportedly believe to be the leader of a prostitution ring.
