A woman in Cape Cod, Massachusetts was left "terrified" after she allegedly discovered a stranger hiding in her backseat while driving home alone in the middle of the night.
According to the Yarmouth Police Department, an officer came across a vehicle he thought was disabled around 1am, only to find a woman outside the car trying to call 911. "She appeared to be scared and upset as she explained to the officer what had just occurred," read a press release.

"As she looked into the back seat, she was surprised to see a man hiding with a coat pulled over his head."
"She said it was so creepy and that she was terrified," cops told WBZ News, as the police report noted that she "began to scream" upon the discovery ... before the male did the same. According to authorities, the "extremely frightened" woman then began to drive "erratically," as the person in the backseat "fell out of the open rear door of the car."
Cops later arrested 36-year-old Jailton Dos Santos and charged him with breaking and entering into a vehicle in the nighttime. He entered a not guilty plea; his bail was set to $3,000.
"The Yarmouth Police would like to remind everyone to make sure they lock their unattended vehicles, especially at night," added authorities.
