ATLANTA, Georgia –

A sandwich shop employee accused of drugging a police officer’s drink earlier this month has admitted he also contaminated the spicy mayo sauce with his semen.

It’s been more than a week since 18-year-old Tanis Ukena was arrested.

Investigators told The Associated Press they didn’t feel comfortable pressing charges until lab results are returned to confirm what was in the drink.

Initial tests indicated meth and THC were present in the beverage.

Ukena denies putting drugs in the officer’s drink, although he did admit to masturbating into the spicy mayo, after police officers said they would find out the truth in labs, and he “better fess up.”

Ukena says that he did not use the spicy mayo when making officer’s sandwich and the mayonnaise-masturbation incident was unrelated.

“I was just bored and unscrewing the cap, I thought – ‘maybe that would feel good.’ I didn’t mean to hurt anyone. Also my lawyer has advised me to say I respect police and any use of force by police is justified in my book.”
