A Subway employee in Layton, Utah, was arrested on Monday 8 August for allegedly drugging a police officer's lemonade with THC and methamphetamine, the active ingredient of marijuana.

The officer starting feeling the effects of being drugged while driving away from the Subway on the Monday afternoon. The employee, Tanis Lloyd Ukena, 18 was arrested in the evening for surreptitious administration of a substance.

According to the jail report, quoted in Deseret News, the officer said that while approached a red light, "he had difficulty getting his foot to move to the brake pedal." The officer drove to the police department where he was observed acting strangely, according to the report: "He was unable to process information and drifted off, and was unable to focus on questions being asked of him."

The unnamed sergeant was hospitalised but later released and given a few days to recover before returning to work. The report says that in surveillance footage Ukena can be seen filling the officer's drink but "for some unknown reason, he walks away from the fountain machine out of camera view. He then returns to the drink where he is seen spending what seems to be an unusual amount of time getting it ready to deliver to the sergeant."

Layton's Police Sergeant, Clint Bobrowski, told the newspaper that he thought the officer was targeted specifically for being in the police, as he was driving a marked car and wearing his uniform, but added "we don't know for sure".

According to Layton Police, a sample from the drink filled by Ukena tested positive for narcotics. Ukena said that he had taken the officer's order but denied drugging his drink.
