SIOUX CITY, Iowa (KCAU) — A Sioux City man was arrested on false imprisonment charges for trapping two victims at his apartment.

According to court documents, Zack Smith, 20, sent an e-mail to his ex-girlfriend pretending to be his father. The e-mail said that Smith committed suicide on Saturday, and the victim could pick up property from his apartment in the Morningside area of Sioux City.

Smith wasn’t deceased, and when the victim and another person went to the apartment on Tuesday around 11:34 p.m., he locked and chained the apartment door. This prevented the victims from being able to leave. Smith had a BB gun in possession.

Smith was charged with two counts of false imprisonment. He was booked in the Woodbury County Jail but has since bonded out.
