Bolton's Croatia striker Ivan Klasnic has been arrested on suspicion of raping a 17-year-old and bailed by Greater Manchester Police.
The 30-year-old was held for questioning by GMP earlier this week before being bailed pending further inquiries.
Police were called to an apartment in Manchester city centre in the early hours of Monday when the allegation was made.
Klasnic was not at the address when the complaint was made and was arrested some time later, sources said.
A spokesman for GMP said: "Police are currently investigating a report of rape in Manchester city centre.
"Shortly before 5am on Monday 25 October 2010, police were called following a report that a 17-year-old had been raped.
"A 30-year-old man has been arrested on suspicion of rape and released on bail pending further inquiries until 1 November 2010."
Police have declined to give any further details about the alleged incident.
Bolton have so far not commented about the allegation.
