A Secret Service laptop containing sensitive information about Trump Tower, details about the Hillary Clinton e-mail probe and other national security secrets was swiped from an agent’s motorcycle in Brooklyn, police sources said Friday.

The computer was taken Thursday morning from the driveway of agent Marie Argentieri’s Bath Beach home, the sources said.

The thief drove up to Argentieri’s home around 8:40 a.m., walked right up to her Bajaj motorcycle and took the items. He was then caught on video fleeing the scene on foot, sources said.

Argentieri told investigators that the laptop held sensitive information about national security, the floor plans for Trump Tower, evacuation protocols and details about the investigation of Hillary Clinton’s e-mail server.

While none of the info pertains to White House officials or foreign leaders, she said it could ultimately compromise national security. Sources told The Post that the laptop cannot be remotely erased or traced.

A black bag with the Secret Service insignia on it was also taken — along with an access keycard, several lapel pins that Secret Service agents are required to wear when protecting the president and other sensitive documents, sources said.

An agency-issued radio, used for closed-circuit communications between agents, was also among the stolen items, according to Politico.

“The U.S. Secret Service can confirm that an employee was the victim of a criminal act in which our Agency issued laptop computer was stolen,” the agency said in a statement Friday.

“Secret Service issued laptops contain multiple layers of security including full disk encryption and are not permitted to contain classified information. An investigation is ongoing and the Secret Service is withholding additional comment until the facts are gathered.”

The NYPD is assisting the agency in their investigation. It is unclear if the theft was targeted or simply a random act.

The black bag and some other items were later discovered at nearby Poly Prep HS by the head of security, Carol Bongnan, and returned to Argentieri.

But the laptop and lapel pins were still missing as of 2:30 p.m. Friday, sources said.

Sources said somebody had brought left it at the school.

Thursday’s heist is just the latest in a long line of public embarrassments for the Secret Service in recent years.

A Congressional investigation in 2015 found that it had transformed into an “agency in crisis” — entrenched in low morale, heavy boozing and dimwitted security decisions.

In Sept. 2014, President Barack Obama’s Secret Service detail allowed a security guard with a gun and three prior convictions for assault and battery into an elevator with him for a photo.

Two years after that, a pair of agents allegedly got drunk and interfered in a bomb investigation outside the building.

In 2014, a man was able to bypass Obama’s security detail and speak to him by pretending to be a congressman.

Most recently, two agents came under investigation after snapping selfies with President Trump’s 8-year-old grandson, Donald III, last weekend.
