CAMBRIDGE, Mass. — A car has crashed into a memorial for the Massachusetts Institute of Technology police officer killed by the Boston Marathon bombers.

Police say the memorial to Officer Sean Collier on the MIT campus in Cambridge sustained “minor surface damage” when the car struck it at about 12:30 a.m. Thursday.

The 52-year-old driver was taken to Massachusetts General Hospital with non-life-threatening injuries. His name was not immediately made public.

The crash is under investigation, but a police spokesman says the driver was not under the influence of drugs or alcohol and the crash does not appear to be deliberate.

The memorial was put up in 2015. Collier was fatally shot on April 18, 2013, just days after three people died in two explosions at the marathon finish line.
