During the incident, which allegedly occurred in the Norrebro district of Copenhagen on the same night that the Gunners exited the Champions League to Bayern Munich, Bendtner reportedly "ran amok", according to Danish tabloid newspaper BT.

The astonished taxi driver reported the incident to the police, claiming: "I have had drunk passengers in my car for 25 years and I have never seen anything like it."
Arsenal are taking the story very seriously and Goal understands Bendtner will be required to give his version of events to manager Arsene Wenger, with the club reserving the right to take internal disciplinary action if he is found to have done wrong.
If true, the bizarre incident only serves to reinforce the 'troublemaker' status Bendtner has established during his colourful time with the Gunners.
Earlier this month the Dane, who is unhappy with the lack of first-team opportunities afforded him at the Emirates Stadium and is expected to depart this summer, suggested that a widely-held perception of him as a "psychopath" has helped to put off interested clubs from signing him.
