28-Year-Old Man Arrested by Boulder Police in Connection to String of Assaults and Threats Involving Chain

BOULDER, Colo. — The Boulder Police Department arrested a 28-year-old man allegedly connected to a series of assaults and threats involving a chain.

Between Thursday and Friday, a series of incidents unfolded in Boulder. The first incident took place at 11:22 a.m. on Thursday when a woman reported being assaulted by a man armed with a chain near 13th and Canyon. Shortly after, between 11:26 a.m. and 11:36 a.m., the Boulder PD received more reports of similar incidents near 16th and Pearl Street.

The suspect took off on a bicycle before officers arrived.

Additionally, there was another incident reported just after noon on Thursday on Baseline Road. Subsequently, on Thursday night, two more individuals came forward to share their encounters with the suspect.

Witnesses told police that the suspect used a metal chain similar to those used to secure bicycles or gates.

Officers arrested a 28-year-old man in connection with the incident Friday afternoon. The department said it is not releasing his name at this time “due to the need for further interviews with victims.”

The man was arrested for second-degree assault, attempted second-degree assault, felony menacing and criminal mischief.

So far, Boulder PD has identified eight victims — seven women and one man. In some cases, the man allegedly struck the victims with the chain, while in others, he reportedly swung the chain “in a threatening manner” and hit a vehicle but did not strike a person, according to police.

Boulder PD said no serious injuries have been reported.

The investigation is ongoing, and additional charges may be filed. Anyone with information about these incidents or others is asked to call Boulder PD at 303-441-1974 and reference case number 25-05785.
