A woman was sexually assaulted after getting into a car she mistook for an Uber, according to Washington, DC, police.

The victim was reportedly waiting for a car around 3:30 a.m. Sunday when the assault occurred in Cleveland Park — just a few blocks from Sidwell Friends, the high school attended by President Obama’s daughters Sasha and Malia.

The woman mistook the silver-colored sedan for her Uber ride, and after she got into the car, was assaulted at knifepoint, local authorities said.

The victim escaped without further injury, and the investigation is ongoing.
