Michael Phelps was driving an SUV that collided with another car in Baltimore Thursday night, but the Olympic gold medal swimmer was not injured, police said.

The female driver of a Honda Accord was "shaken up" and taken to a local hospital as a precaution, police said. Two passengers in Phelps' Cadillac Escalade were not injured, said police spokesman Anthony Guglielmi.

Guglielmi says Phelps has been interviewed by police and alcohol was not a factor. No citations were issued and the accident was being investigated, with a report perhaps available Friday, Guglielmi said.

Phelps won eight gold medals at the Beijing Olympics.
