The Lake County Sheriff’s Marine Unit was recognized for helping save a man who was suffering an opioid overdose while in custody early Saturday morning.

Lake County Sheriff Detective Rebecca Loeb said that the Lake County Sheriff’s Marine Unit was on boat patrol between Grass Lake and Lake Marie on the Chain O’ Lakes when deputies saw a boat commit numerous violations.

A traffic stop was initiated and police arrested a 29-year-old Palatine man for operating under the influence, Loeb said.

The man became unconscious and stopped breathing while he was being transported back to the Marine Unit processing facility.

Loeb said that deputies determined the man was suffering an opioid overdose and administered two doses of Naloxone. He regained consciousness and began breathing normally again.

The Antioch Fire Department transported the man to Advocate Condell Medical Center in Libertyville where he is expected to recover.
