A mid-day fire sent flames shooting out the windows of the top floor of an apartment at Pine Grove Drive on Wednesday.

No one was at home when the fire was reported at 12:36 p.m., said Deputy Chief Mark Baker.

A woman on the first floor of the three-story building said she was alerted to the fire by a neighbor in a building across the courtyard. She said she heard an alarm sounding and notified management, but was unaware that the apartment above hers was burning.

Firefighters extinguished the fire but were still working at the scene an hour later. Baker said the cause of the blaze was yet to be determined.

The apartment is one of six in the building, which is part of a large complex off Oak Street.
