According to TMZ, Lauren Jauregui was arrested on Tuesday night while trying to get on a plane at Dulles Airport.
The report read:
Law enforcement sources say Lauren was stopped at a TSA checkpoint and forced to submit to a secondary search, when a TSA staffer found what appeared to be a bag of marijuana in her carry-on luggage.
Cops were flagged down in the terminal and they promptly arrested the singer.
It appears Lauren was heading for Brazil where the group is set to perform Wednesday night.
