Suspicious Envelopes Sent To Schools In Dedham & Milford, 3 Other States

BOSTON (CBS) - Several suspicious letters were sent various schools in New Hampshire, Rhode Island, Maine, and to at least two schools in Massachusetts on Tuesday.

All of the letters contained white powder, but according to the FBI, field tests on the powder came up negative. Further tests on the substances will take up to 48 hours.

One of the suspicious letters was sent to Dedham Middle School around 1 p.m. School officials there said they were recently warned by the state to be on the lookout for any suspicious mail.

Meanwhile in Milford, crews responded to Memorial Elementary School for a letter that contained white powder. That situation was later contained.

Authorities said there was no danger to students and faculty at either school, and that there was no threat to public safety.

Anyone who received a suspicious letter is asked to call police.

In an unrelated incident, a student in Hingham found a note stating there was a bomb. No time or date was specified, and officers found no bomb at the school.
