The Mexican attorney general’s office says it will begin the process of extraditing recaptured drug lord Joaquin “El Chapo” Guzman to the US.
It said the move was in line with US extradition requests from 2015.
On Friday Guzman was detained and sent back to the maximum-security prison he escaped from six months ago.
Guzman, who was one of the world’s most wanted drug traffickers, escaped from there in July through a tunnel dug in the showers.
The attorney general’s office said that lawyers for Guzman would have three days to file objections and 20 more days to prove them, though that timeframe could be extended, AFP news agency reports.
Guzman was arrested in the north-western city of Los Mochis in his home state of Sinaloa – which he had come to dominate through his drugs cartel.
During the raid, he managed to flee through a drain but was later caught by marines in a shootout.
