Four men and a woman were arrested in connection with incidents at three Atlantic City bars Saturday night. The night started with a fight at the Bungalow Beach Bar at about 10 p.m.. No arrests were made there. The 1200 Degrees Pool Party that started around 5 p.m. was set to end at that time. That led to about 400 patrons exiting onto the Boardwalk. Many of those patrons went to The Royce Social Club at the Tropicana, where another large fight broke out. That was captured on video that was making the rounds on social media. Unruly crowds also were later dispersed from both the Chelsea Pub — which had been shut down — and the Wonder Bar, police said.
