The 19-year-old driver of a car that dragged a convenience store worker -- leaving the worker in critical condition -- after stealing signs featuring David Hasselhoff has admitted his involvement to police, according to the Shelton Police Facebook page.

An employee at a Cumberland Farms in Shelton, Conn., was critically injured while trying to stop thieves from stealing two signs featuring the actor.

The Hasselhoff signs have been a popular target for thieves since the "Baywatch" actor began doing commercials for the convenience store chain last year.

According to police, a black SUV pulled into the parking lot of the Cumberland Farms at 819 River Road around 1:15 a.m. on Tuesday.

A 36-year-old worker noticed a man get out of the SUV and cut down two poster boards with Hasselhoff on them from a light pole and put them in the back of the vehicle. The employee approached the SUV to try and get the signs back and the driver sped away, dragging the victim and throwing him to the ground.

The employee, who has not been identified, flipped backwards and landed on his head, police said. He is listed in critical condition at Bridgeport Hospital.

There were three people inside the SUV, which drove down River Road towards Stratford, according to police.

Police said the 19-year-old man who came forward is suspected to be the driver. No arrests have been made.

Investigators said yesterday that they were reviewing surveillance video and interviewing witnesses. Anyone with information is asked to contact the Shelton Police Detective Bureau at 203-924-1544.

In July 2012, more than 500 cardboard cutouts featuring Hasselhoff were stolen from Cumberland Farms stores in New England and Florida.

Hasselhoff Tweeted about the incident yesterday and said he is "shocked" and "truly saddened" and that his thoughts and prayers are with the man who was injured.
