THE BRONX - Residents say they believe a fire Tuesday at a home on City Island Avenue was arson.

Officials say the fire occurred around 3:50 p.m. on the second floor of the building, but was contained within an hour.

Neighbors say a man who lived on the second floor was in the process of breaking up with his girlfriend. They say the couple was fighting all day and that she later broke in and could have started the fire.

Fire officials have said the blaze appears to be suspicious.
