The accused “A-Train Ripper’’ was ordered held without bail Monday — as a Manhattan prosecutor recalled the horrific details of the suspect’s alleged deadly crime spree.

Homeless double-slay slash suspect Rigoberto Lopez, 21, appeared virtually at the Manhattan Criminal Court hearing, wearing a white COVID-19 protective mask and full Tyvek suit.

He sat silently behind a metal screen as Assistant District Attorney Alfred Peterson launched into a detailed timeline of Lopez’s alleged bloody spree.

“As a result of the defendant’s actions, two people are dead, and two people are very seriously injured,’’ Peterson told the judge.

“It all began on Friday, Feb. 12, at approximately 11:30 in the morning at the subway station at 181st Street and Fort Washington Avenue in Manhattan,’’ the ADA said. “That is an A-train station, Judge.’’

The prosecutor described how Lopez — who has previously been hospitalized for mental-health issues and arrested for allegedly attacking a cop and his own dad — “used a knife and stabbed the first victim, who was seated on a bench in the subway station,’’ wounding the man.

Later that day, Lopez “again used a knife to approach [a homeless man], stabbed him on the train, and [the victim] was found having bled to death on that train car,’’ Peterson said.

But the defendant wasn’t done, the ADA said.

Lopez soon went up to a homeless woman in an A-train car, “used a knife and stabbed her seven times to the chest, abdomen and the arm,’’ the prosecutor said.

“He left the woman on the train, and she was discovered at 207th Street dead in a pool of blood.”

Lopez’s final victim was a man sleeping on a station’s subway stairs, Peterson said.

“The defendant took out the same knife he had used in the other incidents and stabbed this man four times in the back,’’ injuring him, the prosecutor said.

The ADA asked to have Lopez remanded, which Judge Barbara Jaffe agreed to — while also ordering a medical exam for the suspect.

Lopez’s lawyer, Michelle Grant, asked to reserve a bail application for her client.

Peterson noted during the proceeding that Lopez allegedly confessed to his crimes — and was carrying the murder weapon when apprehended. Eagle-eyed cops nabbed Lopez on Saturday evening after noticing he was wearing the same clothing as the susepct caught in surveillance video.

Lopez faces a slew of charges, including felony first-degree murder. He had been arrested at least four previous times, including for allegedly assaulting a cop and his own dad.

Asked by the judge if he understood the charges against him stemming from the bloody weekend spree, Lopez replied, “Si.” A Spanish interpreter was present for him during the proceeding.

His next court date is set for Friday.
