About 1,700 pounds of marijuana, several two-way radios and four ATVs were seized last week in joint agency operations that focused on smuggling groups operating in Southern Arizona's western desert, border officials said in a news release.

On Sunday, officers and Border Patrol agents of the West Desert Task Force found two ATVs, six radios and several batteries and a repeater southwest of Casa Grande. No arrests were made.

Two days earlier, Border Patrol agents assigned to the task force found 43 bales of abandoned marijuana and two ATVs near the Tohono O'odham village of Cocklebur. The pot, weighing 954 pounds, was turned over to the Drug Enforcement Administration.

And on Thursday, members of the task force found an abandoned vehicle and 780 pounds of marijuana south of Vekol Valley, on the west end of Pinal County.

The task force is made up of Border Patrol agents, the Pinal County Sheriff's Office and Immigration and Customs Enforcement's Homeland Security Investigations.
