Patrons in Moreno Valley were lucky to escape tragedy after a speeding car drove through the front entrance of a gym.

Witnesses recorded the harrowing incident at the Fitness 19 gym at 12220 Perris Blvd. The car, a white Volkswagen Golf, can be seen rounding a row of cars in a parking lot before careening into the occupied gym.

Officials say the driver had suffered a medical emergency.

"I got here to teach a class and the whole half of the gym's missing," said Carla Rosa, an instructor at the gym.

One person was transported to a hospital with minor injuries, the Cal Fire/Riverside County Fire Department said, though it was unclear whether the patient was the driver or a gym patron.

The building was red tagged as a result of the crash.
