A nine-hour event dubbed as a "summer beach meet-up" arranged using social media and planned for Friday in Point Pleasant Beach was canceled after authorities warned the gathering could attract a flood of partiers.

A post on Instagram didn't list a specific location for the festivities except the borough's roughly mile-long boardwalk. A similar event, spread on social media, attracted about 15,000 sometimes rowdy revelers to Seaside Park's beach over Father's Day weekend.

Point Pleasant Beach police on Wednesday said the organizers agreed to cancel the party, but authorities would remain on alert.

"However, due to the nature of social media and the exposure that this event has already generated, this agency will be going forward with our planned security measures to ensure the safety and security of all residents and visitors this holiday weekend," police said in a statement on Facebook.

After brawls broke out at the Seaside Park event, Point Pleasant Beach police Chief Joseph Michigan said beachgoers would see a "very high presence of law enforcement," as a precaution based on the latest social media invitation to the borough.

Seaside Park police said they made two arrests and issued about 14 summonses from the June 16 gathering.

Posts on Instagram advertised a "meetup" from noon to 9 p.m. Those postings were updated to show the event as canceled, but one message hinted that a new location might be planned by saying to direct message for details.

It was not immediately clear if both events were organized by the same group. Borough police could not be immediately reached for more information.
