CONCORD, N.H. (AP) — Keene State College students quickly cleaned up from a chaotic weekend on Sunday after violent parties near the city's annual pumpkin festival led to destruction, dozens of arrests and multiple injuries. The parties around the school coincided with the Keene Pumpkin Festival, at which the community tries to set a world record of the largest number of carved and lighted jack-o-lanterns in one place. WMUR-TV in Manchester showed video of a crowd overturning a car, people running from tear gas clouds, street signs being torn down and fires burning in the streets. College President Anne Huot said in an emailed statement that the festival has been promoted by others "as a destination for destructive and raucous behavior" and the college had tried working with the city and campus to prevent unruly conduct. Officials are reviewing photos, videos, media coverage and social media postings to identify those responsible, Huot said, and the most serious offenders could be expelled.
