NEW YORK (CBSNewYork) — A 16-year-old girl has been arrested and charged after a group of teens were caught on video pummeling another girl inside a Brooklyn McDonald’s, according to police.

Aniah Ferguson has been charged as an adult with robbery and gang assault, police said.

As Ferguson was led out of the station by police, she appeared to be smirking and didn’t say anything but “Oh wow,” when she saw the cameras, CBS2’s Weijia Jiang reported.

Family members at Ferguson’s home did not comment.

Police said they were confident that many more arrests are on the way.

As CBS2’s Alice Gainer reported, police said Ferguson was the aggressor and police are also still looking for five other girls between the ages of 15 and 18. They are offering a reward for information.

Police said they have identified the other girls, but it is now a matter of finding them and bringing them in to face charges.

“I’m giving $1,000 of my personal money to find every person that participated in the assault of these young persons, because it was a crime, and I’m not condoning criminal behavior,” said Brooklyn Borough President Eric Adams.
