A Northbrook official declined to offer details but said an incident that forced an area school to be put on lockdown Thursday evening was over.
Northbrook Communications Manager Cheryl Fayne-dePersio called the incident “a long story with a happy ending."
That happy ending includes a 51-year-old Northbrook man being in police custody after a three-hour standoff with police.
Officials said the man fired a gun in a home during an argument with his parents.
Police were first called to the area of Valencia Drive and Willow Road between 4:30 and 5 p.m. They were soon joined by personnel from several departments in the Northern Illinois Police Alarm System.
The man's father told officials his son had a large amount of weaponry, said Northbrook Police Chief Chuck Wernick.
The incident took place on the 2500 block of Salceda Drive, and began at 3:30 p.m. when the 51-year-old fired a gun into a wall in the home during a heated verbal argument with his parents, Wernick said. There is no indication, Wernick said, that the gun was fired at either of the parents. The father left the home after the gunshot and came to the police station to notify them.
When police arrived they were able to persuade the mother, who was not being held against her will, to leave the home, Wernick said.
Police also evacuated nearby Maple Junior High and Glenbrook North High School, cancelling after-school activities there. Police also evacuated neighboring residences.
An NBC Chicago viewer wrote that his daughter called from inside a locker room at the school to tell him that she wasn't allowed to leave the building.
At 7 p.m., police were able to persuade the man to leave the home peacefully, Wernick said. No one was injured in the incident and the man in custody is being medically evaluated this evening.
The man, as yet unidentified, has not been charged, Wernick said, though he expected that a decision on charges would be made Friday morning.
Wernick said police also are in the process of confiscating all the weapons in the home.
Emergency officials closed off numerous residential streets south of Glenbrook North during the standoff and directed traffic on Willow Road away from St. Peter Community Church, 2700 Willow Road, which was used as a staging area for the large number of police personnel called to the scene.
Besides the NIPAS vehicles and a helicopter, police cars from as far away as Franklin Park, Mundelein and Round Lake Beach responded to the scene.
