A fire in a unit at the Pleasant Tower Apartments Friday damaged a unit on the eighth floor.

According to Deputy Fire Chief Martin Dyer, the fire was contained to the eighth floor apartment. One resident was being evaluated Friday afternoon, the deputy chief said.

A second alarm was struck to bring more personnel to the building; the deputy chief said two activated sprinkler heads led to a significant water cleanup operation.

The cause of the fire was under investigation. Firefighters arrived at the building before 6 p.m., and stayed for more than an hour.
