CHEYENNE, Wyo. — A Cheyenne man has pleaded guilty to several charges related to a standoff that occurred in September 2022.
Nikko Viliamu Johnson, 28, pleaded guilty to terroristic threats and aggravated assault and battery via threatening with a weapon last week.
Johnson was part of a standoff with deputies in September 2022. According to a release, the incident occurred on the 800 block of East Jefferson Road in Cheyenne on Sept. 1 when Johnson was contacted on Avenue C. When contacted, Johnson “produced a hand grenade and threatened to pull the pin,” the release stated, resulting in a standoff that led the department to issue a Code Red for the surrounding area, with residents sheltering in place.
The suspect eventually complied with law enforcement and was taken into custody without incident. The hand grenade was later determined to have “no explosive hazards.”
Johnson was originally charged with three counts of aggravated assault and terroristic threats along with a California warrant.
His sentencing is set for May 29.
