O’Brien is suspected of leaving UChicago Medicine Advent Health La Grange Hospital on Wednesday and breaking into a residence in the 5000 block of Harvey Avenue in Western Springs that same afternoon.

He’s accused of then breaking into a second home in the 200-block of Rugeley Road, attacking the homeowner and stealing his car.

O’Brien was arrested Wednesday evening in Willow Springs, while driving the car, police said.

The allegedly attacked homeowner is 70, and suffered a broken arm.

The other targeted homeowner said the suspect got through his back door while his wife and young son were also home.

He said the man stole his clothes before escaping out of the front window, as officers were approaching.

That first house is one of the closest to the hospital.

A hospital spokesperson said they are aware of the incident, and are working closely with law enforcement.
