Police received the call around 7 a.m after the caller read the Facebook post from a man who lived on Garfield Avenue in Danbury. The post indicated the man was suicidal and may have a rifle, Carroccio said.
When officers arrived on scene they found the man in the backyard alone with the rifle pointed at his head, he added.
Officers established a perimeter and as a precaution Immaculate High School and Pope John Paul Center were placed on lock-down, Carroccio said.
Danbury Police Emergency Services Unit and crisis negotiators were called and were able to convince the man to surrender to authorities peacefully at 8 a.m., police said.
The man was transported to Danbury Hospital for evaluation.
