BOSTON (AP) — Boston police are stepping up security at city schools after what were described as "rambling" and "threatening" letters were sent to about a dozen schools.
Police Superintendent William Evans said Thursday that the anonymous, typed letters were sent from Texas and made references to Nazis, al-Qaida, the CIA and weapons of mass destruction.
They made no threats against specific people or schools and did not contain any hazardous materials.
Police do not believe children are in danger.
Evans says the letters appeared to be identical and contained "ranting" and "some crazy language."
Parents learned of the letters through an automated telephone alert from the school department.
City police are working with the FBI to determine the origin of the letters.
