Mount Prospect police are looking for witnesses who might have seen a 79-year-old man crash his scooter Thursday night on Euclid Avenue.
Officer Greg Sill said Saturday police don't yet know how the single-vehicle crash occurred about 7:30 p.m. Thursday near the intersection of Euclid and Crabtree Lane.
All they know is the man, an Arlington Heights resident, was traveling westbound on Euclid when his scooter crashed and he somehow went down in the street.
Sill said the scooter was legally licensed to be on the street.
The driver of the scooter was taken to Advocate Lutheran General Hospital in Park Ridge, where he remains hospitalized because of injuries from the crash, police said.
Those who may have witnessed the crash are asked to call police at (847) 870-5656.
