"The Department of Justice is pleased that the suspected killer of Border Patrol Agent Brian Terry has been captured and will now face justice for this bad crime", said Attorney General Jeff Sessions.
Law enforcement arrested Osorio-Arellanes along the border of Sinaloa and Chihuahua, two Mexican states. The Associated Press reported he is being processed for extradition to the U.S. He was indicted in 2011, along with the other suspects, in federal court in Arizona.
A man was arrested in Mexico on charges related to the 2010 killing of a US Border Patrol agent whose death helped expose the botched federal "Fast and Furious" gun-tracking operation. In the resulting firefight, Terry was killed.
Terry "was killed in a gunfight between US Border Patrol agents and members of a cartel "rip crew" that regularly patrolled the desert along the US-Mexico border looking for drug dealers to rob", said John Kelly, President Donald Trump's secretary for Homeland Security. But ATF agents lost track of about 1,400 of the more than 2,000 weapons involved in the operation, including two that were discovered at the scene of Terry's shooting.
The operation had allowed known drug traffickers to purchase firearms in hopes of the US government being able to document the illegal transit of weapons, but the ATF lost track of more than 1,000 guns, two of which were recovered at the scene of Terry's killing.
Arsenal contract talks on hold until summer-Mesut Ozil
I'm sure there are plenty of other candidates - I'm not anxious about that. "That's what you have to take care of". Arsenal playmaker Mesut Ozil says he will put talks over his future at the club on hold until the summer.
A spokesman for the slain agent's family, Terry's cousin Robert Heyer, declined comment on the latest arrest, citing "the sensitive nature of an ongoing investigation".
Ivan Soto-Barraza and Jesus Sanchez-Meza were convicted of first-degree murder and attempted armed robbery in October 2015.
Rosario Rafael Burboa-Alvarez, who allegedly assembled the "rip crew", was sentenced to 27 years in prison after making a plea deal with prosecutors. Fast and Furious allowed buyers to purchase thousands of guns in the USA and then smuggle them across the border.
Fox News was first to report the arrest. In 2014, Manuel Osorio-Arellanes was given 30 years for his involvement.
The resulting scandal embarrassed former president Barack Obama and led to the resignations of ATF deputy director William Hoover and USA attorney Dennis Burke.
