A woman who claimed to be a nurse made an unusual threat before she was arrested at 4th Street early Sunday morning, according to an arrest report.

Authorities say 24-year-old Shenite R. Joseph was causing a disturbance in the entertainment district — screaming obscenities at an employee — when a Jefferson County Sheriff’s Office deputy asked her to leave.

According to the arrest report, the deputy asked her to leave four times, but she refused.

At that point, authorities say she told the sheriff’s deputy that she is a nurse, and that if the sheriff’s deputy ever came to her hospital, she would put “Clostridium botulinum” in the deputy’s IV.

Joseph was arrested and charged with third degree criminal trespassing and disorderly conduct. Both are misdemeanor charges.
