Police caught Ángel Esteban Aguilar Morales. He is thought to be the leader of Los Lobos. This is a drug group. Morales was wanted for killing Fernando Villavicencio. Mr. Villavicencio was running for president.
Morales was caught at an airport in Mexico. He used a fake name. This arrest is good for police. It shows countries can work together. It is bad for crime groups. These groups cause problems.
Mr. Villavicencio was killed last year. This event shocked Ecuador. Five people were found guilty. They were part of Los Lobos.
Morales tried to go through Mexico. He had fake papers. Police from Ecuador, Mexico, and Colombia helped. Interpol told police to look for him. Morales is now in Colombia. He will face charges.
The President of Colombia said this is good. He said countries worked well. Ecuador's minister said they will catch more leaders.
Los Lobos does bad things. They traffic drugs and kill people. This arrest shows police can stop them. They can catch leaders even if they hide. This is a big step.
