An apartment fire heavily damaged one unit when it broke out in Berea early Friday morning.
It happened on Lester Street just after 1:00 a.m.
Firefighters say flames and smoke were coming from an upstairs window of one of the apartments when they arrived.
No one was inside at the time the fire broke out.
A unit next door had smoke damage. That resident escaped in time.
An investigation into what started the fire is underway.
