A 10-hour standoff at a Ponus Ridge Road home concluded without injuries Saturday morning with the arrest of a 48-year-old New Canaan man accused of making threats against Weston officials, according to New Canaan Police Sgt. Carol Ogrinc.

Scott DeiCas, of 295 Ponus Ridge Road, surrendered without resisting after officers from the New Canaan Police Department's Special Response Team deployed a "flash-bang" explosive to stun him. A dog from the Greenwich Police K-9 unit and his handler then entered the home, according to Ogrinc.

The standoff began Friday night, when police went to execute a warrant at the home, according to Ogrinc.

According to police, DeiCas had made threats to kill Weston school and town officials. DeiCas previously worked for a private school bus company that serviced the Weston school district.

He is being held without bail and is expected to be arraigned in state Superior Court on Monday morning.

No information was available about the charges Weston police filed against DeiCas, and Weston police could not be reached for comment.

The investigation is ongoing, according to New Canaan police, who said they have yet to decide on charges against DeiCas.

On the video-sharing website YouTube, DeiCas maintained a profile in which he posted several video blogs discussing his political views and his use of the hallucinogenic drug LSD. He also describes himself as the leader of an LSD revolution to take over the U.S. government.

"I have made threats of grievous bodily harm to individuals and push LSD here on YouTube," DeiCas wrote in his profile. "I naturally think the FBI is continually monitoring me."

In one video, posted in late January, DeiCas sits dressed in a heavy camouflage jacket and black knit hat and predicts the collapse of the American economic system because of population growth. He then discusses his increasing use of LSD over the previous year and a half, as well as his concern over American use of fossil fuels.

"We have economists who seem to think economic growth is part of the solution, but what they really are talking about is population growth," DeiCas said. "I remember in fifth grade being worried about population growth ... I myself would like to come out in favor of psychedelics."
