Hundreds of teenagers gathered at 31st Street Beach in Chicago on Friday night, leading to chaotic and tense moments.
The Chicago Police made one arrest and recovered a firearm while charges are pending.
The large crowd of teens was estimated to be around 300 to 400, and the chaos began around 6 or 7 PM.
The group dispersed in different directions, and smoke bombs or fireworks caused some smoke in the middle of the large group.
Several Chicago police officers were on hand, and once the crowd took over the beach, they responded with an even larger presence.
Large teen gatherings like this are not new in Chicago and happen typically when the weather warms up.
However, the city was not the only one dealing with such large gatherings as Lombard had to shut down its first night of Carnival due to a similar situation.
No injuries or arrests have been reported from that situation.
