Eleven people and a dog are displaced after a duplex fire in the 900 block of South 33rd Street in Milwaukee. A CBS 58 crew on scene spoke to someone who lives at the property who said that someone they didn't know broke into the house and started a fire. CBS 58 observed someone being put into a squad car. When asked if the fire was being investigated as a possible arson, the Milwaukee Fire Department said the cause is still being investigated by both MFD and MPD. Authorities did tell CBS 58 that someone was detained. It took firefighters a little over an hour to put out the fire Sunday evening.
