Border Protection officers in Texas busted an American citizen attempting to haul $1.5 million in methamphetamine into the U.S. last week, just days after intercepting a Mexican national smuggling 1.2 tons – or $48 million – of the illicit drug, authorities said.

The latest seizure happened on Thursday at the Gateway International Bridge in Brownsville when a 44-year-old woman applied for entry into the U.S., U.S. Customs and Border Protection said Monday.
