NASCAR driver Kurt Busch has met with Delaware police investigating an allegation by his ex-girlfriend that he assaulted her.

Police say Busch and his attorneys met with investigators Tuesday afternoon. An attorney for Busch says he was cooperative and continues to deny the allegations by 36-year-old Patricia Driscoll.

Police spokesman Mark Hoffman says the investigation is continuing and that no decision on whether to file charges has been made.

Driscoll claims she was assaulted inside Busch's motorhome at Dover International Speedway in September, just days after the couple broke up.

In court documents asking that a judge order Busch to stay away from her, Driscoll said Busch was despondent after a poor qualifying run, suggested that he wanted to kill himself, then smashed her head three times against a wall.
