Two nasty fights erupt at Proviso West High School in Hillside, and that has police beefing up security there.
One brawl broke out in the cafeteria on Monday, and another fight took place on Tuesday. Two videos are posted on YouTube.
18 people were arrested, and the students could be expelled.
No one was hurt, and no weapons were used.
Extra police officers are at the school as a precaution.
Authorities say social media is adding to the problem.
“There’s so much misinformation put out on Facebook, Twitter accounts, that we have to react. And when we find threats, we review them and look into it, and try and see if the information is good or not,” said Joe Lukaszek, Hillside’s Police Chief.
School officials insist the school is safe.
