Authorities were called to a Waffle House in south Nashville near Interstate 24 after receiving a report of a naked man and woman with a weapon inside the restaurant.
Staff and customers were evacuated due to feeling threatened as the woman, later identified as 19-year-old Montessa Tate-Thornton, waved the gun around and acted erratically, according to an arrest affidavit obtained by FOX17.
Officers arriving at the restaurant found Tate-Thornton wearing no clothes and "screaming, sweating excessively and making incoherent statements," WKRN reported.
The 19-year-old reportedly admitted to police she had used marijuana and cocaine.
Police took the 18-year-old into custody without incident. Besides the charges linked to the outstanding warrant, Tate-Thornton was also charged with possession of a weapon while under the influence, public indecency, being a felon in possession of a weapon and public intoxication.
The other naked suspect at the restaurant was identified as 34-year-old Larico Nixon, who was also arrested and charged with public indecency, public intoxication and being a felon in possession of a weapon, officials said.
The 19-year-old is expected in court on Monday, according to FOX17.
