Investigators are scrambling to find a laptop believed to contain national security information that was stolen from a Secret Service agent's car in Bath Beach, Brooklyn on Thursday.

The laptop contained floor plans for Trump Tower, details about the Hillary Clinton email investigation, evacuation protocols, and other information pertaining to national security, CBS reports. Sensitive documents were also removed from the car, along with a black bag that was later recovered atop a snow bank at 1533 Cropsey Avenue.

According to a statement from the Secret Service, "Secret Service issued laptops contain multiple layers of security including full disk encryption and are not permitted to contain classified information."

It remains unclear what level of access the agent had. ABC News reports that "authorities are able to wipe the hard drive remotely if needed," while sources tell CBS that the laptop cannot be remotely erased. A police source told the Daily News that "there's data on [the laptop] that's highly sensitive."

Surveillance video from the scene reportedly shows a man in dark clothing exiting a car outside the agent's driveway, then leaving the area with a backpack a few minutes later. The suspect was later seen carrying the backpack on Bay 10th Street and Cropsey Ave, sources tell CBS.

The NYPD is currently assisting the Secret Service with the investigation. We'll continue to update as more information becomes available.
