A Kansas City, Kansas man will serve two years in federal prison for causing a struggle that exposed U.S. Marshals to the drug PCP.

U.S. Attorney Barry Grissom sayes Frederick E. Pendleton pleaded guilty to one count of assaulting, resisting or impeding a federal employee. In his plea he admitted the incident occurred Dec. 30, 2014, when U.S. Marshals attempted to arrest him for violating supervised release in a criminal case.

The marshals went to Liberty Fruit Co., in Kansas City, Kan., where Pendleton was working. Pendleton, 32, resisted arrest, struggling with the marshals. During the struggle, a vial of PCP Pendleton was carrying in his waistband leaked, soaking his groin in the chemical. Two marshals suffered injuries on their hands that came into contact with the PCP. They were treated at a hospital for exposure to the drug.

PCP, also known as angel dust, can cause numbness, loss of motor control, convulsions and hallucinations.

The 24-month sentence will be consecutive to an 18-month sentence in the previous case.
