NASHVILLE, Tenn. -- More than 100 children have joined a class-action lawsuit that stems from an investigation into a summer camp, the Fraternal Order of Police and an officer's union.

Video: Cameras At Children's Camp Lead To Lawsuit

The lawsuit was filed late on Monday and claims that the children who were at the camp are victims because their privacy was invaded.

What happened at the Fraternal Order of Police camp still doesn't seem real to Luke Merithew.

"This was a secluded, private area where we had a huge expectation of privacy that was trounced, violated," he said.

Agents with the Tennessee Bureau of Investigation confirmed that hidden cameras were recording what was happening at the camp. Investigators said the cameras were secretly installed by former Metro police Lt. Calvin Hullett with the hope of capturing drinking and inappropriate activity at the camp.

Many people with ties to the case said it was an attempt to gather evidence that would be used to sway officers to join the Teamsters union and drop the FOP affiliation.

"It was just so unbelievable when we found the cameras and recording equipment," said Merithew.

As a Metro police officer, Merithew served as a counselor at the camp for troubled youth and brought his own children, who helped with the activities.

He said he feels the rights of his children and the campers were violated by the cameras.

"As a parent, I can only imagine what the other parents are feeling," he said.

In the class-action lawsuit, Merithew claims that cameras captured the children naked as they changed out of their swimsuits and then ran into the bunkhouse for showers.

"Hidden cameras and surveillance video cameras certainly have a place in police and law enforcement, but they have no place in private affairs, private property or invasion into people's private lives, and that's exactly what happened here," said Nashville attorney David R. Smith.

Through the lawsuit, the campers hope to teach those behind the alleged scheme to respect the same law they were sworn to enforce.

"If you do something like this, there's going to be consequences and repercussions," said Merithew.

Among the targets of the lawsuit are the Teamsters and Hullett.

It is not clear what was taped, and the video is now evidence in the case.

But the people who filed the lawsuit said what is on the tape doesn’t matter and that the principal of the incident is what counts.

Hullett had no comment for this story. Channel 4’s Marc Stewart was unable to reach a representative from the Teamsters for a response.
