Portland police say the driver of a 2004 Mercedes Benz drove over a sidewalk Monday afternoon and struck an elderly pedestrian before slamming into the doorway of a Starbucks coffee shop on Auburn Street.

Lt. Gary Hutcheson said the driver, a 69-year-old Portland woman, told police she was trying to park her car when her accelerator became stuck on a floor mat causing her to lose control.

Hutcheson said the car went over a curb and hit a 74-year-old South Portland man before striking the building, which is located at the Northgate Shopping Plaza.

The impact of the collision shattered a window but did not injure any Starbucks’ customers. The woman has not been charged.

Portland police would not release the name of the driver. The pedestrian’s injuries were not life-threatening, Hutcheson said.

The crash was reported at 3:23 p.m.
