A 53 year old Chicago bicyclist was left with a brain hemorrhage, fractured ribs and bruised lungs after being struck by a minivan on the city's West Side Saturday afternoon, according to The Chicago Tribune. The male cyclist was walking his bike along the 300 block of South Pulaski Road at the time of the collision. The driver, Sergio Nava, did not stop despite pleas by onlookers. However, police were able to track the man to his home and arrest him thanks to witness accounts. The bicyclist remains in Stroger Hospital and was listed in critical condition as of yesterday. Mr. Nava is being held on $150,000 bond.
