The Danish forward was spoken to by policemen in Copenhagen on Tuesday night; while his team mates were facing Bayern Munich in the Champions League; after a drunken incident.
Bendtner allegedly had a row with a taxi driver and went on to rub his manhood all over the victim’s car.
Wenger has reiterated that Bendtner had no reason to be in Denmark after he told the Gunners staff that he had a slight knee injury.
With his contract up at the end of the season, Wenger is unsure whether Bendtner will ever play for the Gunners again.
“Honestly, I don’t know what happened [in Copenhagen]. I haven’t spoken to him [Bendtner]. The only thing that is for sure, he had nothing to do in Copenhagen,” Wenger said.
“Nobody gave him any permission to go to Copenhagen. He will be fined for that. For the rest, has he created some trouble? I don’t know. I will speak to him today.”
“Look, he’s at the end of the contract at the end of the season.”
