FREETOWN — A weekend house party at 18 Leonard Ave. drew an estimated 1,000 guests, including busloads of people, and "completely inundated" an Assonet neighborhood with cars, traffic and rowdy party-goers, police said.

"We were told it was a small family reunion," said Police Chief Carlton Abbott, noting a daughter of the property owners had been to the station a few days before and requested a detail officer. But the party "completely overwhelmed the neighborhood. We received no cooperation from the property owners."

The party at the 1-acre property off Locust Street started about 9 p.m. Saturday and continued until 3:30 to 4 a.m. Sunday and caused police to call in additional officers from Berkley and Lakeville to handle the traffic. Leonard Avenue also had to be shut down because vehicles were parked on both sides of the road and guests were walking in the middle of the street making conditions unsafe.

Guests purchased wrist bands to gain entrance to the party; police said they didn't know what they paid. There were disc jockeys playing music; seven security guards were on hand; guests were partying outside and inside the property; neighbors were complaining about loud noise; and people were urinating and littering homeowners' properties, according to Abbott.

"I was scared. I was distraught that this was going on in my neighborhood," said Craig Vieira, who lives on Leonard Avenue with his wife and two children. "It looked like I was living on Frat Row."

He said he is upset that police did not shut the party down and did not come to the scene until hundreds of people were there.

Freetown police asked the hosts to stop the noise and they refused, the chief said. "It (the noise) was deafening. They declined to cooperate with us. They said what happens on their property is their business and what happens on the streets is our business," he said.

"It was a party and it was damn the neighbors and damn everyone," said Abbott, adding he empathizes with neighbors since the noise was so loud it could be heard on the other side of Forge Pond.

Abbott said no arrests were made, but the matter is under investigation for possible charges. He said wrist bands were sold and beer was apparently given as part of the fee, which is illegal.

In the interests of keeping the peace with an estimated 1,000 guests, Freetown police decided not to shut down the massive party since hundreds of guests who had been drinking alcohol would all be leaving at the same time. "The decision was made not to go in and create a confrontation. We decided to let it pass and allow people to leave," he said.

The Board of Health plans to bring a complaint for littering, Abbott said.

Police identified the property owners as Lionel Preval and Ingrid Lochard, but Abbott said it was a daughter, Ashley Lochard, who was present at the party and days earlier requested a detail officer from police.

Ashley Lochard gave a terse comment to a reporter when contacted Monday afternoon. "If they were uncooperative with police the party would have been shut down. The party wasn't shut down. That's all I have to say," she said.

The party was promoted with flyers and on social media and was sold out two days earlier, the chief said. "It was an inappropriate venue for that many people. The woman who came in misled police. There was a total lack of respect for the neighbors and a lack of cooperation with police," he said.
