SOUTHINGTON — Federal authorities searched the Motel 6 on Queen Street Wednesday night in connection with investigations into threatening letters and white powder mailed to state and federal offices in Hartford and Bristol.
U.S. Attorney’s office spokesman Thomas Carson was not able to provide additional information on the search but said the investigation is ongoing.
Gary Gravelle, 51, of New Haven, was arrested on Wednesday for failing to comply with conditions of his supervised release. Prosecutors said Gravelle is being investigated in connection with the threats and letters containing white powder sent to several government offices.
In 2013, Gravelle was sentenced in Bridgeport Federal Court to 70 months in prison for mailing numerous threatening letters. He was released from federal prison in November 2015.
Gravelle is alleged to have failed to notify the probation office of a change in residence and failing to comply with mental health treatment requirements. Gravelle appeared before U.S. Magistrate Judge Robert Spector Wednesday and was ordered detained.
Authorities on Wednesday closed down streets in Hartford and Bristol and partly evacuated at least one building following reports of at least five suspicious packages. The structures included a state government building, two office buildings and the federal courthouse.
No injuries were reported and at least two packages appeared to contain baby powder.
