Cops busted a chronic subway surfer who was caught on video while riding on the outside of a C train last week, police said.

Officers went to the Bedford-Stuyvesant home of 22-year-old Isaiah Thompson on Tuesday and picked him up on charges of reckless endangerment, disorderly conduct, and creating a hazardous condition, cops said.

This is at least the fourth time that the dimwitted daredevil has been caught riding on the outside of a train. Thompson was busted in March, September and November 2017 for subway surfing and faced similar charges each time, cops said.

The video that rider Matthew Beary posted to Instagram this weekend shows Thompson looking casual as he hangs onto the outside of the car as it whizzes between two stops. At one point, he even holds on by just one hand and puts the other in his pocket as the train is hurtling through the tunnel. He jumped off when the train entered the Lafayette Avenue station.

“I’d never seen anybody do it before,” Beary told The Post on Sunday. “I’ve seen warnings about it on the subway. I just wanted to take the video because I thought it was awesome and also scary as hell.”

Beary said the woman sitting next to him on the train held her hand to her mouth in shock while the subway surfer rode.

New York City Transit President Andy Byford called Thompson out for his dangerous and potentially train-delaying actions.

“Riding on the outside of a subway car is incredibly dangerous, disruptive, and foolish – it can cause major delays and easily result in death,” Byford said in a statement. “This young man is lucky he ended up in police custody and not in a hospital or worse.”
