Philadelphia police believe the same person is responsible for three unfounded threats at city schools Friday morning.
Police say threats were phoned in to Masterman, Ben Franklin High, and the School of the Future between 8:30 and 9:30 Friday morning. All three schools were evacuated while police investigated.
The threats were determined to be unfounded and classes resumed at each school by 10:30 a.m.
Detectives are looking into the threats. There's no word on any arrests.
