NASCAR Sprint Cup Series driver Kurt Busch is under investigation by Dover, Delaware police for allegations of domestic assault, according to a recent report from ESPN.

The allegations apparently involve an incident that occurred inside of his motorhome at a race.

Police issued this statement Friday, according to Foxsports.com:

"The Dover Police Department can confirm that an investigation is being conducted based on an allegation of domestic assault that is alleged to have occurred in the City of Dover involving Mr. Busch. These allegations were brought to the Dover Police Department on Wednesday, November 5th at 2:00PM. At this time, the department is still investigating the victim's claims and will not have any further comment on this matter in order to preserve the integrity of the case. The Dover Police Department will release further information as it becomes available. We appreciate the public's and media's patience in this matter and are confident that the department is taking the proper investigative steps to ensure the case is resolved appropriately."

NASCAR had this to say in response to the criminal investigation:

"NASCAR is aware of the investigation involving driver Kurt Busch. We recognize the seriousness of this matter and are actively gathering information from all parties, including law enforcement authorities and Stewart-Haas Racing. It would be inappropriate for NASCAR to comment further on this matter until we have more information."

Busch, a member of Stewart-Haas Racing, is currently in Avondale, Arizona practicing at Phoenix International Raceway.
