DENVER (CBS4) – An undercover operation lasting two days resulted in the arrests of 10 child predator suspects, including a teacher at a school in Denver.

The 10 men were arrested Jan. 20 and 21 on charges of attempted trafficking of a minor for sexual servitude, attempted solicitation of a child for prostitution and attempted sexual assault on a child.

The cases will be prosecuted by the Adams County District Attorney’s Office.

Authorities told CBS4 they are concerned because, “We are concerned there may be more victims since one of the suspects picked up in this sting was an elementary school teacher.”

David Hocker was a teacher at Warren Village in Denver before he was terminated.

“Obviously it is very concerning. The reason we put that information out in a press release is so that people can know where this individual was at,” said Adams County District Attorney Dave Young.

Another suspect arrested is a public school employee but does not have access to children at his job.

Three of the men arrested were in the country illegally from Mexico which means they will face deportation proceedings after their cases move through the court system.

“To protect the most vulnerable in our society, we must be proactive — identifying and apprehending predators who have decided to take advantage of our children,” said David A. Thompson, special agent in charge of HSI Denver, in a statement. “HSI is proud to do this important work in collaboration with our state and local partners, who are vital to the success of these missions.”

The operation, led by U.S. Immigration and Customs Enforcement’s Homeland Security Investigations, was assisted by detectives from the Adams County Sheriff’s Office, the Commerce City Police Department and the Colorado State Patrol.
