Police in Peru have arrested a former airline owner whom the United States accuses of being a "drugs kingpin".
Mr Zevallos has never been convicted of a crime
Fernando Zevallos is suspected of cocaine trafficking, murder and witness tampering, Peru's state attorney for drugs crimes told Associated Press.
He is already being tried in Peru over an attempted shipment of cocaine to Mexico in 1995, which was foiled.
He maintains his innocence, reportedly saying he was the victim of abuse of authority as he was taken into custody.
Peruvian television showed him being led handcuffed into the headquarters of the police anti-drugs unit on Saturday.
Mr Zevallos was placed on a US list of suspected drugs traffickers in June of last year.
His US assets and those of his airline, Aero Continente, were frozen, leading to its collapse.

Under US legislation, people placed on the US list of drug traffickers and their businesses are denied access to the American financial system.
Mr Zevallos has previously been accused of trafficking cocaine, laundering money, tampering with witnesses and ordering murder, but has never been convicted.
The latest arrest appears to be linked to the trial of drugs trafficker Jorge Chavez, reportedly an enforcer for Mr Zevallos.
Mr Chavez pleaded guilty to drugs charges in Miami 10 years ago and became an undercover informant, AP reports.
The US Drug Enforcement Administration says it has launched more than 30 investigations into Mr Zevallos.
He insists he is the victim of character assassination, overzealous US drug agents and business rivals.
