A Maryland man was hospitalized with serious injuries after being driven about 100 to 200 yards on the hood of his SUV during a carjacking in Gaithersburg on Wednesday afternoon, police said.

The victim was injured when he fell from the SUV, said Shiera Goff, a spokeswoman for the Montgomery County Police Department. He is expected to survive, Goff said.

About 3:30 p.m., police were called to what they initially thought was a pedestrian having been struck by a car in the area of Whetstone Glen Street.

“It turned out to be a carjacking,” Goff said.

The crime took place in the car owner’s neighborhood. He jumped on the hood of his car as it was being stolen, Goff said. “He was trying to stop them,” Goff said.

As of 5:45 p.m., police were looking for two people — one who drove off in the victim’s vehicle, a black Lexus SUV, and the other who left in the vehicle the two arrived in, a late-model gold Chevrolet Malibu.
