MERIDEN — Three employees were quarantined after a suspicious substance was found in an envelope at a city business Friday.
Emergency crews responded to The Money Source, 500 S. Broad St., about 1:15 p.m. and cordoned off a side entrance to the building with yellow tape.
Police Sgt. Christopher Fry said state police, the Department of Energy and Environmental Protection and a member of the FBI also responded. The substance was determined to be inert, though further information was not disclosed.
Fry said the employees quarantined did not fall ill and appear to be in “good health.”
Landlord Wes Clow said the envelope had a return address and there was no danger to other people in the building.
Fry said officers are investigating the incident and are exploring if they will file charges. No specific threat was made, he said.
On Friday, authorities also investigated a white powder scare at the Islamic Center of New London in Groton.
The substance, which has been sent to the state crime lab for analysis, was found in an envelope at the mosque just before 9 a.m. Police say a 43-year-old man was exposed to the powder, but was not injured.
The Connecticut chapter of the Council on American-Islamic Relations says the envelope contained a letter that included derogatory comments about Islam.
On Sept. 12, police investigated after a letter containing white powder was discovered Congregation Adath Israel in Middletown.
On Sept. 5, suspicious packages were found at four downtown Hartford buildings. At least two contained baby powder. A 51-year-old man is being investigated in connection with those incidents.
