NAVARRE, Minn. - Four Orono police officers were treated at a local hospital after being exposed to an unknown chemical during a welfare call.
Officers were called just after 9:00 p.m. Monday to the 3300 block of Shoreline Drive in Navarre. When they arrived squads found a male locked inside his vehicle, unresponsive.
When the officers tried to remove the man he became combative. They then smelled a strong chemical odor inside the vehicle.
The suspect was eventually removed from the vehicle and police say the officers started feeling light headed and burning in their throat and eyes.
Four Orono officers and the man they rescued were taken to North Memorial Emergency Room.
As of 4:00 a.m. Tuesday the officers had been treated and released, and the male victim was still being treated for chemical exposure.
Orono Police are investigating the incident, assisted by the Long Lake Fire Department and the Chemical Assessment Team from Hopkins Fire Department.
Authorities have not released any information about the kind of chemical the officers encountered.
