Mexico has arrested a man linked to the suspected massacre of 43 students who went missing in 2014 in Guerrero state , a government source told AFP on Monday .
The students ’ disappearance became a symbol of the gruesome violence blighting the country , as well as – many claimed – the murky links between powerful drug cartels and corrupt officials .
Angel Casarrubias “was detained last Wednesday in Mexico State ,” said a federal government official , who asked to remain anonymous as the person does not have authorisation to speak on the matter .
The students had commandeered five buses to travel to a protest on the night of September 26 , 2014, but were attacked by municipal police in the city of Iguala , Guerrero .
Prosecutors initially said the officers delivered the 43 teacher trainees to drug cartel hitmen , who killed them , incinerated their bodies and dumped the remains in a river .
However , independent experts from the Inter -American Commission on Human Rights have rejected the government ’s conclusion , and the unsolved case remains a stain on Mexico ’s reputation .
Prodh , a human rights organization that advises relatives of the victims , said on Twitter that the arrest was “relevant” because Casarrubias , who had been on the run since 2014, “could contribute to clarification in the case .”
He is the brother of Sidronio, Mario and Adan Casarrubias , who are believed to be the leaders of the Guerreros Unidos ( United Warriors ) cartel . They were captured several months after the students went missing .
The federal prosecutor’s office believes Sidronio Casarrubias was responsible for the attack.
