An undercover deputy was critically injured but is recovering at a hospital after being pinned between vehicles during a traffic stop, the Palm Beach County Sheriff’s Office said.

John Pyrzyk, 47, of West Palm Beach, is accused of backing a maroon Dodge pickup truck into the deputy while trying to escape arrest, officials said.

It started just before 1 p.m. Thursday with reports of a suspicious vehicle, reports the Sun Sentinel.

The Dodge reportedly sped away when deputies tried to conduct a traffic stop. They did not chase the pickup, but undercover deputies followed it at a distance in unmarked cars, officials said.

When the pickup pulled into an apartment complex parking lot about 2 p.m. it was surrounded. A man and woman got out but Pyrzyk threw the truck in reverse and backed away, striking the deputy and a patrol car before hitting a fence. Pyrzyk jumped out and ran but a K-9 team caught him, investigators said.

The deputy—whose name has not been released—was taken to St. Mary’s Medical Center with injuries that were not considered life-threatening, officials said.
