PHOENIX -- The Maricopa County Sheriff's Office is cracking down on drug trafficking at the border.
The sheriff's office is entering the final phase of a large-scale drug enforcement interdiction launched this month.
"Operation Borderline" has netted 10 pounds of heroin, 35 pounds of methamphetamine, more than 1 ton of marijuana and 10 arrests, Sheriff Joe Arpaio said at a news conference Friday. His office has also seized $35,000 in cash and a few vehicles.
During the final push, Arpaio plans to utilize helicopters, a fixed-wing aircraft and all-terrain vehicles to probe the desert for drug smugglers.
"We have to do something about the drug problem," he said. "That's going to be a new priority for this office, and try to do something about the border, too."
Arpaio said heroin in particular is a problem nationwide and said violent crimes are often tied to drugs.
"We're sending the word out to the drug traffickers that we're going to be in the desert and we're going to arrest them," he said.
