The 33-year-old, who has previously played for Manchester City , Sunderland, Fulham and Blackburn, is now plying his trade for Stockholm-based side AIK.
Naijasportsxtra.blogspot.com sourced from the Mirror of the UK that the Nigerian has landed himself in hot water after the incident outside a nightclub in the area.
A brawl took place after Etuhu and two other men were denied entrance to the venue, with police called to the scene.
The Nigerian has fronted up and released a statement via his club's website.
He said: "I want to confirm that I am the AIK player that was involved in the incident that has been reported in the media during the last two days.
"I'm coming forward because I don't want any more speculation surrounding my team-mates about who was involved and I have always stood up for my actions.
"I have talked to my club and the police about what in my opinion happened on Sunday night, and I will today file a report to the police about what I believe caused the incident and the way the security staff acted.
"I have no further comments since it is now an ongoing police investigation."
AIK's director of football Björn Wesström added: "It's never good news when anyone in our club is involved in this kind of matter.
"I have been in contact with the player and had a good conversation with him in which he calmly gave his version of the story."
