An 18-hour standoff involving an armed man blockaded in an apartment and Oak Park police ended without injuries at 5:20 a.m., Friday morning after the person surrendered himself and was transported to a local hospital for a mental health evaluation, according to the Oak Park Police Department.

Wednesday Journal has reached out to the police for more information. The Journal has also reached out to Thrive Counseling Center, which partners with Oak Park police for mental health calls, to see if any of its crisis interventionists played a role in resolving the conflict.

Police first arrived in the 1100 block of North Harlem Avenue at about 11 a.m., Thursday in response to calls reporting an armed individual had barricaded himself in his apartment. The area was then closed to traffic as officials negotiated with the distressed individual.

Oak Park police were supported in efforts to safely resolve the situation by specialists from the Cook County Sherriff’s Office and officers of the River Forest Police Department.

Harlem Avenue reopened to traffic as normal Friday morning.
