Oswego Police say they do not believe there to be a threat to the public after an incident on Tuesday afternoon.
Around 3:30 p.m., police were dispatched to a home in the 500 block of Torrington Court for a domestic incident.
While officers were responding, police say the caller reported that an ex-boyfriend of one of the residents had just fled from the home in a red Chevrolet after allegedly threatening and gesturing to shoot one of the residents.
Officials say no gun was actually displayed, however, the caller reported the man was known to possess a gun.
A responding officer encountered the vehicle heading east on Wolf's Crossing Road between Douglas Road North and Douglas Road South, at which time the driver allegedly pulled off the road and fled from the vehicle leaving it on the side of the road.
The man was last seen running into the subdivision at the northwest corner.
Police say they immediately converged on the area, established a perimeter and began searching for the individual.
A canine search was conducted and a drone was deployed to aid in searching the area, including the grounds of the Fox Bend Golf Course.
Wolf's Crossing Rd. was shut down between Southbury Blvd. and Douglas Rd. South and two schools and a child care facility nearby were placed on lockdown out of caution.
Police were able to establish phone contact with the man and determined he had been picked up by an acquaintance and had traveled out of the Oswego area.
Police did not identify the man. They say they are still actively investigating the incident and do not believe there is a threat to the community.
Numerous agencies assisted, including the Naperville Police Department Canine Unit, Montgomery Police Department, Kendall County Sheriff's Office and the Illinois State Police.
