MILWAUKEE (CBS 58) -- One person was rescued from an arson fire near 18th and Keefe late Wednesday, Jan. 15. 

Authorities were called to the scene just before 11 p.m. 

Police say there were five occupants in the residence, a 30-year-old, 19-year-old, 6-year-old, 4-year-old, and 4-month-old. 

The Milwaukee Fire Department says they arrived at the scene to find heavy fire on the first floor and an occupant on the second-floor porch roof attempting to escape. Firefighters safely brought the resident to the ground safely.

MFD says the fire was complicated by two hydrants that were not working, requiring additional hose lines to more distant hydrants. A second alarm was requested to assist with the response.

The fire was brought under control after establishing a positive water supply.

Police determined the cause of the fire to be arson, and a 56-year-old was arrested in connection. Charges are pending review by the Milwaukee County District Attorney's Office. 

MFD also confirmed the home sustained extensive damage and is uninhabitable. The Red Cross is assisting the displaced residents.
