Boulder police on Wednesday evening arrested a sword-carrying man they allege cut another man earlier in the day.

Cody Scott Parker, 26, faces a first-degree assault charge, and a woman in his company, Aneta Urban, 38, faces a conspiracy charge, according to a news release.

Police did not say where they arrested the pair but indicated that they are acquainted with the victim and were arrested without incident.

Boulder police spokeswoman Laurie Ogden said the incident began when police began receiving calls of a suspicious man with a sword in his backpack near 14th and Walnut at about 3:30 p.m.

“Shortly after, we got calls from (a bank on Pearl Street) that a man was chasing someone with a sword,” Ogden said. “The next time he was seen, he was at 14th and Canyon.”

Ogden said the man, later identified as Parker, pulled a knife out of the victim’s backpack and slashed at the victim, who held his hand up defensively, sustaining a serious injury in the process. He was taken to Boulder Community Hospital’s Foothills Campus for treatment.

Following the attack, police said Parker headed toward the Bandshell at Broadway and Canyon Boulevard, where he climbed onto a bicycle and headed east along the bike path. Per radio scanner traffic, a man carrying a large sword was seen near McGuckin’s Hardware store on Wednesday evening.

The University of Colorado announced in an alert to students that a man armed with a sword injured a person near 14th and Arapahoe at about 4 p.m., prompting a search of the area and a brief lockdown of the CU Children’s Center.

Officials announced at 5:15 p.m. that the children’s center lockdown was lifted.

Parker does not appear to have any criminal record in Colorado, according to online court records. Urban has a conviction for false reporting in Boulder County and numerous traffic offenses.
