Seniors living in an Atlanta high-rise building got a scare after a fire broke out overnight.

The fire happened at the Friendship Towers on Northside Drive around midnight.

Firefighters tell FOX 5 that senior residents had to be evacuated after someone set fire to trash on the 13th floor of the building.

Thankfully, the building’s sprinkler system was able to keep the flames under control and no one was injured.

Arson investigators are now working to find out who started the blaze.

If you have any information about the fire, call the Atlanta Police Department.
