An arrest has been made in connection with a fire that destroyed a Foster City condominium complex and displaced more than 150 residents, authorities said.

The suspect was taken into custody without incident and booked into the San Mateo County Jail.

Investigators say unattended grill caused fire

What we know:

Investigators determined the Aug. 2 fire was caused by an unattended gas grill on the exterior balcony of a first-floor condo unit at 815 Sea Spray Lane.

The blaze destroyed the 51-unit Spinnaker Cove condominium complex, which remains fenced off and red-tagged because officials say the building is at risk of collapse.

Firefighters injured

Four firefighters were injured while battling the blaze and rescuing residents. Officials said they were treated for injuries ranging from second-degree burns to smoke inhalation.

Authorities said the building suffered catastrophic damage and is considered a total loss after flames spread through the attic and insulation.

Seven people trapped on the third floor were rescued by the San Mateo Consolidated Fire Department as residents evacuated with children and pets.
