House Party Concerns
Governor Phil Murphy is concerned about a recent surge in cases, with house parties accounting for more than 125 new cases in the Garden State.
Police in Jackson Township broke up a large party with more than 700 people Sunday night, with partygoers ignoring social distancing and mask regulations.
Officers monitored the area and observed a large crowd. The homeowner was contacted and told officers he had rented out the residence on Airbnb and was hosting a large party.
The homeowner then left the area as an estimated 200 additional people arrived at the residence.
The crowd at the residence grew to an estimate in excess of 700 people, police said, with well over 100 vehicles parked in the area as the department began receiving 911 calls from other homeowners in the area.
Officers then began to clear the crowd, and the Ocean County Prosecutor's Office was contacted. Charges were filed against the homeowner and party organizer.
"We're not saying you can't gather, but it is literally irresponsible. You're playing with fire if you gather indoors without face coverings, without social distance in close proximity," Murphy said. "So please, I'm asking parents, we're asking kids themselves, it's OK to gather. Behave yourselves."
