BALTIMORE: 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. Phelps' SUV had a crumpled hood and was on a tow truck. The gray Accord had considerable damage on the front driver side. Phelps has had brushes with the law in the past. USA Swimming suspended him earlier this year for three months after a British tabloid published a photo of him using a marijuana pipe. The Richland County, S.C., sheriff's office investigated the photo but found there wasn't enough evidence to charge Phelps. In an earlier incident, Phelps pleaded guilty to driving while impaired shortly after he won six golds and two bronzes at the 2004 Athens Olympics. A Maryland state trooper had pulled him over after Phelps ran a stop sign. He was sentenced to 18 months' probation. Most recently Phelps earned five golds and a silver over eight days at the world swimming championships earlier this month.
