As reported by Piers Eady of the Mirror, the misfiring Gunners forward was quizzed after a window was smashed and the door to a gym was kicked, leaving damage on the property:
Neighbours allegedly said they had heard the sound of doors being kicked in and windows smashed in the gym and pool area.
CCTV footage also emerged apparently showing people at an outside door to the flats just after 1am.
Bendtner took to Instagram to explain himself, insisting he was merely attempting to deal with a malfunctioning door.
Police earlier questioned residents who reportedly saw a man entering through the smashed window and trying to kick his way through the locked gym door in the early hours of the morning, as noted in Eady's report.
"I could hear people smashing the doors," a resident said. "I shouted for them to stop but a man yelled abuse at me. You could hear the door being smashed time and time again."
Bendtner was cautioned by the police after training on Nov. 25.
"A 25-year-old man from Bushey has been cautioned for criminal damage," a spokeswoman from the local police confirmed. "He was released and is no longer in custody."
So often outlined as an egotistical outlaw, Bendtner has had several previous brushes with the law since moving to England.
As noted by BBC News, he was banned from driving for speeding at 103mph back in 2012, while later that year, he was found guilty of driving without a license or insurance, per Paul Byrne of the Mirror.
The latest report is an unwanted distraction for both player and manager, as Arsene Wenger attempts to keep his league leaders settled in pursuit of silverware.
Regardless of his minimal impact on Arsenal's campaign so far, Bendtner remains the only genuine cover for Olivier Giroud until the Gunners can find alternatives in January. Theo Walcott can play through the centre, but Bendtner offers the strength and height that Giroud brings to the Arsenal attack.
Arsenal are about to enter a busy period of the season, which will see them play seven games in less than a month. The physical strain will likely take its toll on Giroud, so Wenger will need Bendtner's mind in the right place.
Wenger must keep his mind focused on Arsenal, at least until January. Disturbances like that reported at his own house will do little to ease his manager's mind.
