U.S. Customs and Border Protection officers at the DeConcini crossing in Nogales seized meth and heroin from three women from Anchorage, Alaska, last weekend.
Agents working the pedestrian crossing sent the three women, ages 33, 30 and 29, for further inspection on Friday.
A search revealed that two of the women were concealing meth within their body cavities, according to CBP.
The third woman had a package of heroin hidden in her purse.
The drugs weighed more than a pound and had a combined value of $11,000. The drugs were seized and the women were arrested on suspicion of drug smuggling.
