A report of smoke caused some tense moments at a senior living home late Sunday night.

San Antonio firefighters were called to the Ernest C. Olivares Senior Community Residence just before 11 p.m. after a report of smoke on the second floor.

Crews contained the smoke to one room and no one had to be evacuated, fire officials said. 

Fire officials believe the cause of the smoke was electrical due to a malfunction with some lights.
