Police in upstate New York are investigating rape allegations against Chicago Blackhawks star Patrick Kane, the Buffalo News reported on Thursday, citing two law enforcement sources.

Kane, 26, has an off-season home in the Buffalo suburb of Hamburg, where a woman has accused the four-time NHL All-Star of sexual assault, according to the unidentified sources cited in the newspaper.

The law enforcement sources said the woman went to a hospital and tests using a rape kit were performed after the incident last weekend.

"We are aware of the police investigation and are following developments," said the NHL's Frank Brown, group vice president of communications.

Kane, who has not been charged with any crime, is scheduled to bring the Stanley Cup to Buffalo this weekend to celebrate the Blackhawks' third championship in the last six years.

"We are aware of the matter and are in the process of gathering information," the team said in a statement. "It would be inappropriate to comment further at this time."
