LAYTON, Utah -- (KSTU) -- A Layton Police sergeant is recovering after someone tried to poison him.
Authorities said the sergeant stopped by the Subway restaurant on Highway 193 for lunch Monday.
When he took a sip of his drink he tasted chemicals and said he knew something was wrong.
The lawman said he came to a red light on his way back to the station and his body wouldn't let him hit the brake. He made it safely back to the station and was taken to the hospital.
Authorities said the man's drink tested positive for marijuana, THC and methamphetamine.
Sgt. Clint Bobrowski said the surveillance video from Subway shows what happened.
"The suspect was seen taking the sergeant's order, filling his drink," Sgt. Bobrowski said. "The suspect left the sergeant's drink on the counter and left the picture frame. In the video you can see him returning with something in his hand and then leaning over the sergeant`s drink for an unusual amount of time. The suspect then provide the sergeant with the drink."
Officers arrested 18-year-old Tanis Lloyd Ukena after seeing him on the surveillance video.
Authorities said they believe this is an isolated incident.
