Kendall and Kylie Jenner prompted the call of a SWAT team on Saturday after they were mobbed by fans at a New Jersey mall.

The Keeping Up with the Kardashians stars were promoting their new fashion collection for American retailer PacSun at the Garden State Mall and hundreds showed up to meet them.

The building’s Fire Marshall forced the teenage sisters to leave because the crowd got out of control.

A tactical police force was called in to deal with the mass turnout.

Kylie tweeted a plea to fans as the situation became dangerous.

“Hey everyone at Garden State mall...please try to stay calm in line or they will shut down the event and we really want to meet you guys!” she wrote.

Kendall later logged on to tell their followers the girls were being forced to leave.

“'What an amazing turn out! Can't believe the fire marshal had to come AND the swat team had to show up! You guys are crazy, I love it! Thanks,” she wrote.

The half-sisters of Kim, Kourtney and Khloe Kardashian on Friday were promoting their new fashion venture in New York.

The crowd at the Roosevelt Field Mall in Garden City was manageable and the girls were able to finish the meet-and-greet.

Kendall, 17, and Kylie, 15, released a statement about their new venture with the California-based company on Friday.

“From concept to design, we really enjoyed the process of creating a fashion line that reflects our personal style! We’re so proud of the collection and excited to finally share it with our fans,” Kendall said.

Pieces from the collection range in price from $24.50 to $79.50.
