NASHUA — Six people were arrested as police and management at the Junkyard Nightclub shut down the facility Saturday night because of an unruly crowd.

Local authorities responded to the nightclub at 522 Amherst St. in the early evening and returned around 8:45 p.m. for reports of fights breaking out inside the club where a battle of the bands competition was taking place.

“They didn't have enough bouncers to maintain control of the event,” said Lt. Francis Sullivan of the Nashua Police Department. “It got a little out of hand.”

At least one band didn't bring security with them to the club, where a crowd of several hundred people gathered, according to police. A significant amount of police officers responded to the disturbance, said Sullivan, who said police and Junkyard staff jointly decided to shut down the event and close the nightclub.

“As a result, some people became unruly. They were obviously not happy about this,” Sullivan said, explaining there was a lot of yelling, swearing and shoving.

Four people allegedly refused to leave the nightclub after repeatedly being asked to exit, two individuals are accused of resisting arrest and two others allegedly assaulted police during the incident.

At least one officer was pushed during the disruption, and another was shouldered, said Sullivan.

Those people arrested were: Joseph Pare, 27, of Windham, charged with criminal trespass and resisting arrest; Nathan Valle, 20, of Saugerites, N.Y., charged with criminal trespass and simple assault on a police officer; Bryan Nowell, 25, of Stoneham, Mass., charged with criminal trespass and simple assault on a police officer; John Tapia, 21, of Manchester, charged with disorderly conduct; David Lee Southworth, Jr., 36, of Nashua, charged with disorderly conduct and resisting arrest; and Kelsey Cabral, 20, of Windham, charged with criminal trespass.

Police said no one was injured in the incident. According to Sullivan, this was probably the largest disturbance police have responded to at the Junkyard since it opened.
