CNN is reporting that Olympic gold medal swimming champion Michael Phelps was involved in a traffic accident in Baltimore, Maryland, on Thursday night, but was uninjured.
Phelps was driving one of two vehicles that collided at an intersection about 9 p.m., police spokesman Anthony Guglielmi told reporters at the crash scene.
The female driver of the second vehicle was transported to a local hospital as a precaution, Guglielmi said. Phelps' two passengers were also uninjured.
Video from CNN affiliate WBAL showed Phelps' black Cadillac Escalade at the crash site.
The crash was under investigation, Guglielmi said. Phelps was being interviewed, he said, but would not disclose where the interview was taking place. WBAL was reporting as of about 10:45 p.m. that Phelps' interview was complete and he had been sent home.
Guglielmi said authorities would determine whether alcohol was involved in the crash, but said that is standard procedure for any crash. He added that alcohol was not believed to be a significant factor in the Phelps crash, or it would have been obvious to responding officers.
