A person familiar with the police investigation of Chicago Blackhawks star Patrick Kane tells The Associated Press that it involves something that happened between the player and a woman in her 20s.

The person spoke on condition of anonymity Monday because authorities have not revealed any details of the investigation being conducted by Hamburg police.

Hamburg Police Chief Gregory Wickett confirmed the investigation last week, saying it involved something that may have happened at Kane's home outside of Buffalo on Aug. 2. Wickett said police were gathering information and awaiting results of forensic tests.

Kane is from Buffalo, and was selected first overall by Chicago in the 2007 draft. He has helped the Blackhawks win three Stanley Cup championships in the past six seasons.
