Warwick's police chief says a threat to elementary school students in three communities mentioned beheading.
Col. Steven McCartney tells WPRO-AM that the threat specified that "beheading is planned." He called the nature of the threat targeting children in Warwick, Cranston and Johnston chilling.
Johnston police received the anonymous threat by mail on Tuesday. Police say officers will be at every school in Johnston, Cranston and Warwick through Friday.
Several parents said they'll keep their children at home. McCartney says the schools may be the safest place to be.
Cranston Supt. Judith Lundsten says recess will be canceled and students will not wait outside but will enter immediately.
Lt. Matthew Moynihan, a state police officer working for Cranston police, said authorities have not determined any validity to the threat.
