A strange odor led to the evacuation of a gym in Rancho Bernardo Wednesday night, officials confirmed.
The 24-Hour Fitness located at 17170 Bernardo Center Dr. was evacuated just before 7 p.m. after members and staffers noticed an odd smell wafting through the gym.
The fire department was called to the scene to investigate the root of the issue.
As of 7:30 p.m., the building remained under evacuation as investigators worked to determine the cause of the odor, and whether or not it may have been caused by a gas leak. San Diego Gas & Electric officials were also called to the scene.
By 8 p.m., San Diego Fire-Rescue public information officer Lee Swanson said SDG&E investigators had determined the odor was not stemming from a gas leak.
Fire officials believe the smell came from some sort of electronic equipment burning.
Swanson said evacuaees were evaluated on scene for any possible injuries but no one was transported to the hospital. Officials did not say exactly how many people were led out of the building during the incident.
Gym members will likely not be let back inside the facility tonight, as officials are still investigating the cause of the burning smell.
