NASCAR driver Kurt Busch involved in police investigation

A statement from the Dover Police Department said that a victim came forward with the allegations on Wednesday, however it declined to offer any further details while the claims are being investigated.

"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," read the department's statement.

"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."

NASCAR responded with its own statement on Friday.

"NASCAR is aware of the investigation involving driver Kurt Busch," said the series.

"We recognise 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."

The Armed Forces Foundation, which has worked with both Busch and his ex-girlfriend Patricia Driscoll, has already announced that it is severing its ties with the 2004 Cup champion until the investigation has been completed.

"Given the serious nature of the allegations, the Foundation has suspended its association with Mr. Busch," said AFF chairman of the board Pat LaFrieda in a statement.

Busch participated in the opening practice sessions for this weekend's Cup race at Phoenix.
