Four people were arrested Saturday night following a series of incidents that broke out across three Atlantic City venues. The trouble began around 10 p.m. when a fight at Bungalow Beach Bar coincided with hundreds of patrons spilling onto the Boardwalk from a nearby pool party. The crowd moved on to The Quarter at the Tropicana, where another large brawl erupted and was captured on social media video. Police later dispersed unruly crowds at two other local bars, ultimately charging four area residents with obstruction and disorderly conduct.
