One resident was treated for smoke inhalation in Erie County Medical Center after a fire routed the occupants of a Linwood Avenue apartment house about 3 a.m. Thursday.

Spokesman Michael DeGeorge said the two-alarm fire did $50,000 damage to the building at 175 Linwood. The cause appears to have been careless smoking, he said. The injured person was identified only as a man in his 30s.
