KEENE, N.H. (AP) — The first person arrested as a result of asking the public for images of the violent disturbances near a family-friendly pumpkin festival in Keene, has been arraigned.

Police say 19-year-old Jacob Clark of Chichester threw a beer bottle at a police officer last month. He was charged with reckless conduct.

WMUR-TV reports prosecutor Jean Kilham said Thursday police tracked down Clark partly through his Facebook postings and a video appearance. He posted having intentions to “rage and let my stress out.”

Public defender Alex Parsons said Clark’s post also mentioned he tried to help keep things safe. Parsons argued against Clark’s 7 p.m. to 6 a.m. curfew as a bail condition.

Nearly 100 people were arrested after parties got out of hand near the Keene Pumpkin Festival.
