The head of an NYPD transit district in Queens was stripped of his command amid allegations that he had police reports falsified to downplay subway crimes on his watch, sources tell The Post.

Capt. Steven Hyland, who headed Transit District 20 in Jamaica, allegedly had two sergeants and a lieutenant under his command falsify reports — even forging signatures — to play down assaults and grand larcenies in the subway system, the law enforcement sources said.

In one incident, Hyland allegedly ordered a cop to change a complaint marked “legit” to snuff it out.

“This dude was so bad, he victimized the victim,” one source said.

Now, the veteran cop has been reassigned to a lesser detail in the Brooklyn court system after bringing internal charges against him Wednesday.

Police brass received one complaint regarding Hyland falsifying a report – prompting the department to launch its own audit, finding three more, sources said.

“When the police commissioner learned this was an investigation she told all parties to take the matter incredibly serious,” another source said. “He was transferred immediately.”
