It appears a 2-alarm fire in Lancaster city was electrical.
It happened just before 6:00 yesterday evening in the 400 block of College Avenue near Franklin and Marshall College.
Officials say the home is broken up into three apartments, and a young woman on the third floor noticed the lights flicker while she was reading in her room.
She then found smoke coming from a ceiling fan in the bathroom.
Flames spread to the roof, but were quickly contained.
At least one firefighter suffered a minor injury.
