Two Missouri police officers have been placed on paid administrative leave after a prosecutor accused them of lying about what happened when they tried to arrest a suspect for a parole violation last year.

Marshall Police Sgt. Roger Gibson said Wednesday that officers Tyler Newell and Josh O'Bryan will remain on leave pending an internal investigation. He says an undetermined outside police agency will also investigate.

The officers claimed in their police report that the suspect, Carl Roettgen, tried to shoot one of them while they were trying to arrest him for a parole violation in a Wal-Mart parking lot in May 2015.

Saline County prosecutor Donald Stouffer announced Monday that he was dropping the three assault charges against Roettgen because video and other evidence contradicted the officers' accounts. Among other things, he said he found no evidence that Roettgen had a gun.
