A homeless man with a rap sheet was identified Thursday as the wannabe mugger shot by an off-duty NYPD cop after he tried to rob her and her husband inside Penn Station.

Jahmar Stewart — who has four prior arrests — was charged with attempted robbery and assault over the Wednesday evening rush hour mayhem on a train platform at the Midtown transit hub, authorities and sources said.

Stewart, 32, allegedly tried to mug the couple — both off-duty police officers who were on their way home — before he was wounded by the quick-acting woman on the Long Island Rail Road’s track 18 at around 7 p.m.,  law enforcement sources said.

“The couple spent the day at home alone, resting after spending most of the night in the hospital,” a police source said of the married pair Thursday.

“The husband had several bumps on his head, where he was punched from the suspect and a laceration to the ear,” the source said. “They also received a steady call from cops concerned about their welfare.”

Stewart, whose last known address is a Brooklyn homeless shelter, was taken to Bellevue Hospital, where he was listed in stable condition as of Thursday.

He was most recently arrested on Aug. 8 for allegedly attacking another resident at the facility on Albany Avenue, police said.

The 43-year-old victim was gathering his belongings around 11:15 p.m. when he got into an argument with Stewart, who slugged him multiple times, according to police.

The victim was taken to the Kings County Hospital Center for treatment of scratches to his face and shoulder, cops said.

The top charge in that case was third-degree assault, which is not bail-eligible, and Stewart was released on his own recognizance, according to the Brooklyn District Attorney’s Office. 

Before that, Stewart was busted on a petit larceny charge July 16 for allegedly stealing fruit juice worth only 69 cents from a bodega on East New York Avenue, authorities and sources said.

That case was adjourned in contemplation of dismissal at arraignment, prosecutors said. 

Stewart was arrested a day earlier at the same Albany Avenue housing facility on menacing charges for allegedly jumping on another resident’s bed and flashing a knife, the DA’s office said. 

He was released on his own recognizance by Judge Orville Reynolds, over prosecutors’ request for supervised release, according to court records. 

Stewart was also arrested June 10 for allegedly hitting another fellow shelter resident in the head with a tree branch, according to the criminal complaint. 

He again faced the non-bail-eligible misdemeanor assault charge, and was released on his own recognizance, the sources said. 

Penn Station is located in the confines of NYPD’s Midtown South Precinct — a tourist-packed area that also includes Times Square, Grand Central Terminal and Madison Square Garden.

That area has seen about a 20% decline in robberies so far this year, down to 241 from the 301 reported at this time in 2024, according to the latest NYPD data, updated Sunday.

Wednesday night’s mayhem came just a day after another off-duty cop became a crime victim in the city’s subway system. 

Homeless career criminal Aaron Walker, 28, allegedly shoved an off-duty NYPD cop, 24, onto the subway tracks in an unprovoked attack at the Third Avenue L train station in the East Village around 7:30 p.m. Tuesday, cops said.

Walker allegedly hurled the officer — who was heading home from the United Nations General Assembly security detail, according to sources — onto the downtown roadbed, sending him to the hospital.

The unhinged attacker was picked up by police a short time later and faces a top charge of attempted murder.

He had 17 prior arrests and was recently granted supervised release in connection to another attack on the rails, authorities said.
