Pittsburgh Fire, Police and EMS and University of Pittsburgh Police responded to a report of an explosion and possible fire on the 3300 block of Forbes Avenue shortly after 3 p.m.

Firefighters encountered heavy smoke billowing from the underground garage of the SkyVue apartments. Firefighters entered the garage and located the source of the smoke, which came from an apparent electrical fire in a column inside the garage. Duquesne Light came to the scene to cut the source of electricity to the fire, and the fire burned out. 

Most residents self-evacuated. Firefighters also went floor to floor to evacuate all tenants. No one was injured.

The Fire Investigation Unit, made up of investigators from Pittsburgh Fire and detectives from Pittsburgh Police, will investigate the cause of the fire. Initial indications suggest it was electrical.

Sprinklers activated in the garage but not in living areas. There was no report of water or smoke damage to the apartments.

Forbes Avenue was closed while First Responders were on scene.
