Two people were overcome by smoke when an apartment building in Wilkinsburg caught fire this afternoon. Some of the residents are shaken up following the fire. The Brittany Apartments on Penn Avenue caught fire around 1:45 p.m. on the eighth floor of the complex and burned for about 15 minutes. Pittsburgh Bureau of Fire Chief Ed Farley said it could have been a lot worse. When firefighters arrived, it didn't take them long to get the fire under control but they are working to figure out what caused the blaze. "Right now, county arson is coming out to look over the situation," Chief Farley said. "Where the fire did start, where it originated, we don't know that right now. They will bring the dogs to see if it's something suspicious."
