Federal authorities have seized more than 6,100 pounds of marijuana in two separate incidents in southern Arizona.
U.S. Border Patrol agents from the Douglas Station investigated suspected narcotics smuggling east of Douglas on Tuesday afternoon.
Two Mexican men were arrested and a search of their pickup truck turned up more than 1,500 pounds of marijuana, valued at $777,000.
The names of the two arrested men weren't immediately released Wednesday. Agents said they worked in collaboration with the Hedglin Forward Operation Base.
The vehicle was seized and the narcotics were turned over to the DEA.
A short time later, agents from the Nogales Station came across an abandoned van near the Mexico border.
They say 189 bundles of marijuana weighing more than 4,600 pounds were found inside the vehicle. The marijuana is valued at more than $2.3 million.
Both the vehicle and the marijuana were seized and taken to the Nogales Station for further processing.
