On Thursday, Disney (DIS) began implementing security measures at Walt Disney World, including installing metal detectors at the entrance to its parks.

Disney World will also stop selling toy guns and will prevent guests over the age of 14 from wearing costumes. The moves come after a man was arrested when he tried to bring a gun into the Magic Kingdom last weekend. In response, more security guards, local law enforcement, and specially trained dogs have been patrolling the parks.

Guests entering Disney World Thursday are greeted with signs that outline the new security guidelines.

“We continually review our comprehensive approach to security and are implementing additional security measures, as appropriate,” said Jacquee Wahler, director of communications for Walt Disney Parks & Resorts.

Disney World’s current security measures, which include a bag search, are still in place, and the metal detectors will serve as an additional layer. Guests will be randomly selected for secondary screening.

The response from fans has been positive overall, and many have taken to social media to show their support.

Universal Orlando and SeaWorld (SEAS) have also followed suit and now have metal detectors at entry points, reported the Orlando Sentinel. The increased safety measures are also extending across the country where Disneyland and Universal Studios will use detectors, as well.

Disney hasn’t said how long the detectors will remain in place.
