Authorities have cleared an Apple Valley High School security guard after an altercation between students in June.

Jason Rieck had been placed on leave by the Rosemount-Apple Valley-Eagan School District, pending an investigation into the incident.

Apple Valley Police Capt. Nick Francis said there are no criminal charges being sought against the security officer. The School District cleared Rieck of any wrongdoing. He will remain an employee of the district and has no discipline in his record, according to the district, which said it could not comment further.

The Council on American-Islamic Relations, a Muslim advocacy group, said Rieck had used excessive force in removing a Muslim student during an altercation at the school on June 1.

The altercation took place between the 15-year-old female Muslim student and a male student. The advocacy group said the male student harassed the girl and called her a terrorist.

Rieck and a school resource officer intervened in the altercation.

The officer called for backup, and the female student was brought to the Apple Valley Police Department and later released.

Rieck's lawyer, Philip Villaume, said in a news release that school officials are not taking any disciplinary action against his client.

"There were allegations made that Mr. Rieck's conduct was racially motivated and those allegations were proved to be false," he said in the statement.
