Duncan D. Bell, 33, of Waukegan

Prosecutors say a bystander who tried to stop a domestic disturbance in Waukegan was “pistol-whipped” and seriously injured by a man, who was later arrested and found with a machete.

Duncan D. Bell, 33, of Waukegan, was charged with felony aggravated battery causing great bodily harm.

Officers and paramedics responded around 12 p.m. Wednesday to Harry Poe Manor, 300 Lake Street in Waukegan.

Lake County Assistant State’s Attorney Francis DeRosa said during a Thursday bond hearing that officers learned the victim and Bell are neighbors.

Bell had been arguing with a female in the elevator of the building.

The woman slapped Bell a few times and Bell appeared ready to hit the female back when the victim intervened with the two, DeRosa said.

Bell allegedly hit the male victim, who was also in the elevator, in the head with a gun, DeRosa said.

Officers found Bell outside the building holding a machete. No gun was recovered.

Paramedics transported the victim to Vista Medical Center East in Waukegan for treatment.

Officers noted that the victim’s eye was bloodshot and bleeding.

DeRosa said the victim was later determined to have suffered a broken bone near his eye in addition to the abrasions.

Lake County Judge Theodore Potkonjak ordered Bell held on a $100,000 bond and ordered him to have no contact with the victim.

Bell remains held in the Lake County Jail on a $100,000 bond.

A preliminary hearing is scheduled for September 8.
