The Fort Worth Police Department swore in their newest group of cadets Thursday morning—16 children fighting cancer and other serious illnesses.

At the ceremony, each child was outfitted in their own police uniform and received a badge that read “real hero” from a receiving line of Fort Worth officers

Damon Cole, the Fort Worth officer who dresses up as superheroes and visits children in the hospital, organized an entire day of “training” activities for the junior officers.

The children and their families rode in police cars on the driving track, took pictures with the police helicopter and mounted control, and got to see demonstrations by the SWAT and K-9 units, Cole posted on Facebook.

After their training, the junior officers got to try out their new cop skills by arresting a “bad guy.” One child, Luke Nelson, got to put his dad in handcuffs and completed the arrest by giving his “bad guy” a good tickle.

The Fort Worth Fire Department were also on hand to help the kids be firemen for the day. The children and their families got the chance to take pictures in a fire truck and put out a fire in the department’s training building.

The Fort Worth Police Department and Heroes & Cops Against Childhood Cancer both posted the ceremony on Facebook.
