A Kansas McDonald’s worker was accused of putting cleaner in a deputy's drink. Trevor Hockaday, 22, was charged with one count of aggravated battery of a law enforcement officer.

Allen County police charged Hockaday for putting a peroxide-based cleaner usually used to clean the restaurant’s counters. The incident took place on Sept. 12 prompting an investigation. If convicted of the felony charge, he faces 20 years behind bars.

The deputy allegedly picked up the food and drink -- an iced tea or a Coca-Cola -- from the McDonald’s drive-thru while Hockaday was working. Local media KOAM reported that the deputy experienced flu-like symptoms after consuming the drink.

"He thought he caught the bug, but we found out two weeks later when an employee came forward and told the police department,” Allen County Sheriff Bryan Murphy told the Wichita Eagle. The report added that another worker told officers that Hockaday added “four little squirts” of the cleaner to the cop’s beverage.

“In today’s day and age, not only us in law enforcement but citizens as a whole, there’s enough going on out there that we have to worry about ... now my guys are cautious about going through that drive through,” Murphy told the Wichita Eagle. “We all chose this line of work to protect and serve. Now my guys have that concern of is my food safe.”

The Iola McDonald's owner Glen Nichols issued a statement saying that the fast food chain is working with authorities.

"In our restaurants, nothing is more important to us than the safety and well-being of our customers. We are very disappointed by the allegations made regarding the behavior of one of our former crew members. This kind of behavior goes against our food safety standards and is not tolerated. Our organization will take all appropriate measures to gather facts and will work closely with authorities in their investigation," Nichols said.

In July, a McDonald’s employee was caught on camera body-slamming a customer and beating her after she tried to fill her water cup with soda. The brawl broke out at a McDonald’s outlet in Las Vegas.
