ORANGE - Local and federal investigators say three people have been arrested for robbing a string of RadioShack stores across the state.

Police say seven locations were burglarized, and that in each incident, the suspects walked in, made an employee direct them to a storage room and then stole cellphones. In all, they say $300,000 in phones were taken from the stores.

Authorities say they have reason to believe 20-year-old Lorraine Outlaw, 21-year-old Forenza Murphy and 22-year-old Michael Carbonell are responsible for the crimes. They say Outlaw and Murphy are from Bridgeport.

Detectives have identified 22-year-old Demetrius Wilkes as a fourth suspect, and say an arrest is imminent.
