Foxborough police arrested 101 people and took 466 more into custody at the New England Country Music Festival in Gillette Stadium Friday and Saturday evenings, police said today. The charges included being a minor in possession of alcohol, disorderly conduct, resisting arrest, trespassing, assault and battery, and assault and battery on a police officer, Foxborough police Sergeant Richard Noonan said. One person was charged with operating a vehicle under the influence of alcohol, and another charged with drug possession. Those arrested ranged from teenagers to people in their 50s, Noonan said. The two-day event was headlined by country singers Kenny Chesney and Tim McGraw. At the 2009 New England Country Music Festival, at which Chesney also performed, police arrested 114 and placed at least 228 people in protective custody. Six people were charged with assault and battery in 2011 after a melee at a McGraw concert in Attleboro. Noonan declined to say whether police provided extra security for this year’s event in Foxborough.
