CHICAGO HEIGHTS, Ill. (STMW) — A man arrested after a south suburban house party got out of control early Saturday later escaped from police custody outside a Chicago Heights hospital.

Cook County Sheriff’s police were called to a house party near 14th Place and Woodlawn in Ford Heights between 2 and 3 a.m. after the party got out of control and people began spilling out onto the street, according to sheriff’s office spokeswoman Cara Smith.

Officers had to use pepper spray to get the crowd under control, Smith said, and a 32-year-old man arrested for obstruction of justice was taken to St. James Hospital in Chicago Heights as a precaution because he had been sprayed.

After he was treated and cleared at the hospital about 5 a.m., the man resisted being placed into a squad car and managed to run away, Smith said.

Police know who they are looking for, but declined to release the man’s name Saturday morning because he has not yet been charged with a crime, according to Smith.

He remained at large as of 11:45 a.m. but is not believed to be dangerous, Smith said.
