KANSAS CITY, Kan. (AP) — A Kansas City, Kansas, man has been sentenced to two years in federal prison for causing a struggle in which U.S. Marshals were exposed to the drug PCP.

U.S. Attorney Barry Grissom says 32-year-old Frederick E. Pendleton pleaded guilty to one count of assaulting, resisting or impeding a federal employee.

Pendleton struggled with U.S. Marshals as they attempted to arrest him at Liberty Fruit Co., where he was employed, in December 2014 for violating supervised release in a criminal case.

Two marshals were injured when their hands made contact with PCP that leaked from a vial in Pendleton’s waistband. They were treated at a hospital.

Pendleton’s 24-month sentence will be consecutive to an 18-month sentence in the previous case.
