A SHOCKING video has emerged of the moment a smartly-dressed commuter drags an unconscious passenger off a train.

The clip shows the businessman hauling the man onto the platform at the Blue Line’s Wardlow Station in Long Beach, California.

The unconscious man had just suffered a medical seizure on the train, according to horrified witnesses who saw what happened.

Others passengers claim the man did not want to wait on the train for paramedics to arrive to treat the stricken man.

“So this dude is passed out on the train and this motherf*****g white boy is doing the motherf*****g most,” a man who recorded the incident says.

“This motherf*****r just yanked him off the f***ing train so he won’t have to stop and miss his f***ing ride.”

No one else on the train complained of having to wait for paramedics to respond, according to the witness.

The suited man is later seen getting off the train and kneeling down to check the man’s pulse. He then claimed he was “being responsible” by removing the unidentified man from the train.

In a statement obtained by The New York Post, transit officials said an investigation into the incident is ongoing.

Police in Long Beach are now trying to identify the man in the video and will determine if any criminal charges are warranted, said spokesman Rick Jager .

“Obviously, this is very disturbing and we never want to see this on our system,” the statement read.

“We’re getting all the facts including reviewing the video from the train and the platform, and we’ll share more details when they’re available.

"If someone is in distress, we encourage people to call 9-1-1 for medical assistance.”

Detectives are reviewing the video and will coordinate with the Los Angeles District Attorney’s Office to determine if any criminal negligence took place.
