Notorious drug lord Rafel Caro Quintero, who was behind the 1985 killing of a US DEA agent, has been captured by Mexican forces nearly a decade after breaking out of a Mexican prison and returning to drug trafficking , an official in the Mexican navy announced on Friday.

No further details were given about the capture, AP News reports, Telegraph reports.

Cara Quintero was freed in 2013 after 28 years in prison when a court overturned his 40-year sentence for the kidnapping and murder of US Drug Enforcement Administration (DEA) agent Enrique “Kiki ” Camarena in 1985. The brutal assassination marked a low point in US-Mexico relations.

Cara Quintero, the former leader of the Guadalajara cartel, had since turned to drug trafficking and launched bloody turf battles in the northern Mexican border state of Sonora.

President Andres Manuel Lopez Obrador has claimed that he is not interested in arresting drug lords and prefers to avoid violence.
