City leaders are calling for more after-school resources after large crowds of teens gathered outside the Barclays Center on Friday.

Teens from multiple school districts gathered outside of the Barclays Center and the Atlantic Terminal Mall for the second straight afternoon, following the start of classes.

Teens were seen in viral social media videos throwing balloons and footballs and running across traffic in large groups.

"I saw some fights. I saw some people throwing things, but people were just out here because they heard about it online," said one teen, who observed what happened Thursday.

In response, police placed large barricades outside of the Barclays Center and the Atlantic Terminal Mall on Friday evening, where teens are already not allowed unless supervised by an adult.

Local leaders say the gatherings show a failure of available after-school resources that teens can go to.

"It's a beautiful day, kids should be having fun outside with their friends. But this is one of the most dangerous intersections, and this is not the place to do it," said Council Member Crystal Hudson, adding that she wants to work with the teens to give them more positive activities.

The students agree that there is a lack of resources available to them.

"It is kind of our fault. We can't be trusted to be out here. But at the same time, everything's expensive, and closing early. There needs to be more stuff for kids to do, something more fun than this," said teenager Che, adding, “There are no places to hang out like that here, no basketball courts. That's why kids keep coming back."

A new youth and basketball center right across the street is set to open this month, but leaders say one center isn't enough.

"It's misdirected energy, and it's misguided energy. There's a disconnect between kids and adults," said Community Board 8 President Brian Saunders, who says he has been walking around during the gatherings to talk to teens about what their goals are.

"These kids want to be pilots, they want to do music, and we can't just tell them where to go. We have to listen to why they are telling us. They don't have that option," he said.
