Police and emergency personnel from Pierce County Fire & Rescue responded to the scene, 3921 S. Meridian, at about 1:45 p.m. Monday after receiving a report of a crash, said Capt. Ryan Portma of the Puyallup police.
Two adults and a toddler were in the car when it crashed through the side of the Harborstone Credit Union branch there. They sustained minor injuries but did not require hospitalization.
A credit union employee was briefly trapped by the wreckage but did not appear to be seriously hurt, either. The employee was taken to Goodsam Hospital as a precaution.
It was not immediately clear whether it was driver error or a mechanical malfunction that caused the car to crash, police said.
Damage to the building was estimated at $25,000 to $30,000.
