STAMFORD - Stamford police say a driver is facing multiple charges after he struck a motorcyclist and took off. 

Police say 40-year-old Byron Luna-Perez was driving a black Honda when he struck the motorcycle at around 9:30 p.m. Sunday at the intersection of West and Baxter avenues.

The motorcyclist, identified by police as Willard Kemp, was thrown from his bike and suffered life-threatening injuries, officials say. News 12 is told he was taken to Stamford Hospital, where he is being treated for head and internal injuries.

Police say Luna-Perez took off, but was apprehended thanks to a witness who got his license plate number. Luna-Perez was arraigned Monday on charges of driving under the influence and evading the scene of an accident.

Luna-Perez was also driving without his license at the time of the crash, police say.
