One of the men attacked in Penn Station by a dagger-wielding maniac with “rage in his eyes” was stabbed through the temple and suffered a traumatic brain injury.

The grisly details surrounding Hector Deleon’s alleged Sunday rampage, in which four other people suffered slash or stab wounds, were revealed Friday as the madman was arraigned on seven counts of attempted murder.

Deleon, 51, allegedly plunged his double-sided blade into one victim’s head, piercing their left temporal lobe, according to a criminal complaint.

The unidentified man was left with a cerebral hemorrhage and traumatic brain injury.

The wild-eyed suspect, who sources said was likely high on drugs during the stabbing spree, knifed four other people in the random attack and slugged two others in the face,
the complaint alleged.

One of the victims, Henry Obadiah, 60, was traveling home to New Jersey when Deleon set his sights on him.

“The crazy guy locked his eyes on me and just roundhoused me! Clocked me right in the face and I was like, ‘What the f–k?’ And I heard the guy on the escalator say, ‘He’s got a knife! He’s got a knife!’” Obadiah said.

“I didn’t realize I had just been slashed in the face,” he recalled.

“He went at me to kill me! I saw the rage in his eyes,” Obadiah said of the homeless madman.

Deleon was also charged with five counts of assault and six counts of attempted assault.

“This was a terrifying attack in the middle of Penn Station during an incredibly busy time in New York City,” Manhattan District Attorney Alvin Bragg said in a statement.

“We will pursue accountability in this matter and continue to prioritize preventing these types of random and violent incidents from occurring in the first place.”

Deleon’s hefty criminal record includes at least seven past arrests since 2008, including a 2022 stabbing in Newark eerily similar to the Penn Station attack.

In that case, he was accused of stabbing a man in the neck with a six-inch blade, according to court records. He pleaded guilty to aggravated assault and received just two years of probation when he was sentenced the following year.

Deleon was held without bail at his Friday arraignment.
