Adam Lambert spent several hours in a Finnish jail after being arrested for fighting with his boyfriend Sauli Koskinen outside a Helsinki gay bar, according to The Hollywood Reporter. Petri Juvonen, who is in charge of the police investigation, said the former ‘American Idol’ runner-up and the winner of the 2007 Finnish version of ‘Big Brother’ were arrested on charges of assault around 4 am on December 22, outside DTM (Don’t Tell Mama).

Both Lambert and Koskinen were brought in for question as police look into four possible assaults. The dispute that led to their arrests started in one of DTM’s back rooms, and the two were kicked out as a result. But the two continued fighting in the street outside.

Ex-Miss Helsinki Sofia Ruusila was celebrating with Lambert and Koskinen when the fight started, and said she tried to get in between the two once they started fighting. The singer accidentally hit her in the process.

Lambert traveled to Finland to celebrate Christmas with Koskinen’s family. Prior to the arrest, Lambert tweeted in Finnish “Helsinki is a beautiful city full of beautiful people!”

It’s unclear if Lambert and Koskinen will face charges in connection to the incident, and when the singer will be able to return to the U.S. But Juvonen has said the two have been released, following police questioning.
