A Mexican judge has ordered a US-born suspected drug lord known as "La Barbie" held for 40 days pending an investigation into organized crime and other charges.
Valdez was born in Laredo, Texas, and has been living illegally in Mexico.
The Attorney General's Office announced the judge's decision in a statement Saturday. Valdez was captured Monday following a yearlong investigation.
