Chicago police say they are investigating an accusation that Chicago Cubs All-Star shortstop Starlin Castro sexually assaulted a woman last fall, but no charges have been filed at this time and Castro’s representatives deny the allegation.

WBBM Newsradio in Chicago reports that the unidentified woman, who is in her 20s, was at a River North nightclub Sept. 29 when she met Castro. After 3 a.m. CT, she went with a friend to his apartment, where she alleges that the assault took place.

The woman went to a hospital the next evening and police became involved, while Castro left for his offseason in the Dominican Republic, according to the report.

The police are now hoping to talk to Castro, a source told ESPNChicago.com. Castro has been scheduled to return to Chicago next week for the Cubs Convention.

Jay K. Reisinger and Michael P. Gillespie, attorneys for Castro, issued a strongly worded statement.

“We are aware of certain allegations that have been made against our client, Starlin Castro,” the statement says. “We have thoroughly investigated this matter, and we are confident that these allegations are baseless. Given the sensitive nature of this matter, we cannot comment any further.”

The Cubs issued a statement, as well.

“We are aware that a police report was filed regarding an incident involving Starlin, but we have received limited information,” the statement said. “While this is something we take very seriously, there is not enough information to make any further comment or take action at this time. We are hopeful when the facts are brought to light, Starlin will be cleared of any wrongdoing.”

Castro has been tabbed as the new face of the Cubs franchise under Theo Epstein, the club’s new president of baseball operations.

In his second year in the big leagues, Castro made his first All-Star team last season, batting .307 with 10 home runs, 66 RBIs and a league-leading 207 hits.
