Darien police are investigating another incident in which a resident received a letter and suspicious powder over the holiday weekend.
On Monday afternoon, police responded to the Tokeneke section of Darien to investigate a suspicious powder and a threatening letter in a mailbox, police said. Investigators turned the items over to the FBI after conducting preliminary tests.
This morning, a resident of Rainbow Circle called police to report also receiving a letter containing a suspicious powder.
The resident told police that he or she received the letter on Saturday and threw it out, thinking it was a prank, but contacted police this morning after learning of the incident yesterday in the Tokeneke section of town.
Darien Police, the F.B.I, Stamford Bomb Squad and the Darien Fire Department responded to the residence and the homeowner has not shown any signs of illness.
No one else is believed to have been exposed, police said.
The substance was isolated and there was no threat to neighboring houses or Tokeneke Elementary School, which is located nearby.
Police said there is no reason to believe that the two incidents are connected and conclusive results on the tested substance could take up to five days.
