Two police officers worked together to save the life of a passenger who became unresponsive inside a vehicle in Riverwoods last week, authorities said.

The Riverwoods Police Department responded at 2:15 p.m. last Thursday to the area of Lake Cook Road and Portwine Road to assist the fire department with a medical emergency.

A passenger in a vehicle became unresponsive and the driver pulled over and began CPR, Riverwoods Police Chief Bruce Dayno said.

Riverwoods Police Officer Joe Peterson arrived and took over CPR.

Deerfield Police Officer Barry Schwartz arrived later and used an automated external defibrillator (AED).

The AED delivered a shock and Schwartz took over CPR from Peterson.

The Lincolnshire Riverwoods Fire Protection District arrived and transported the person to NorthShore Glenbrook Hospital in Glenview for treatment.

The person was breathing and had a pulse when they were transported.
