BELLINGHAM, Wash. -- Five people were injured Tuesday morning when a car smashed through the front of a Starbucks store.

Lt. Steve Felmley said the 70-year-old man was pulling into the store parking lot at 1031 W. Bakerview Road around 9:30 when his Chrysler 300 accelerated and crashed through the front window of the building.

Five customers -- four women and a man -- were injured. One of the women was pinned against a wall, and all five have been taken to a local hospital.

None of the injuries was believed to be life-threatening.

The impact sent glass, furniture and debris flying through the store as the car careened through the store and into the back wall, causing it to partially collapse.

Dr. Don Stevens was inside the store and said he didn't even see the car coming.

"We were sitting at one of the tables here and heard this horrible crash," he said. "The lady that I was with, the car hit her chair and sent her flying to the floor."

Stevens said when the car hit the back wall the tires were still spinning.

"It happened very, very quickly," he said.

The driver was not seriously injured. Police said he is from Arlington, Texas and was visiting family in the area.  

The driver told investigators the car was a rental and he doesn't know what happened to cause him to crash through the store.

"He said the car was just running and wouldn't stop," Felmley said. "He had no explanation as to why that occurred.

"He's very sorry this happened. He's glad the injuries weren't more serious."
