The officer, who works as a football supporter liaison officer, is reported by the Metro daily to have attacked the AIK Solna supporter after recognising him while on a night out.
The officer is accused of having punched and hit the 18-year-old in the face.
“First a punch and then with some type of hard implement,” the teenager said in police interviews.
The officer was out with friends on October 23rd and visited several bars in the Gamla Stan area of central Stockholm. He met a group of AIK supporters at the Central station metro and began talking with them.
It was then that the officer recognised the 18-year-old as one who has featured in several police investigations into trouble at AIK football matches and the drunk police officer then went on the attack, according to Metro.
The officer has also been charged with assaulting an officer in a separate incident on the night in question. He is accused of having after he intervened to prevent uniformed officers from arresting one of his party.
