AKIPRESS.COM - Mexican authorities searching for 43 students who disappeared after a protest last month are investigating a suspected mass grave, reports BBC.

Attorney General Jesus Murillo Karam said the testimony of two arrested members of a drug gang had led them to the site, in southern Guerrero state.

Reports claim that the students were handed to the gang by local police.

Earlier this month another mass grave was found, but the bodies unearthed did not belong to the students.

Dozens have been arrested and the state governor has resigned over the case.

The mayor of the town of Iguala, where the abductions took place, his wife and the police chief are all being hunted by the authorities.

They allegedly ordered the police to hand over the students to gangsters.

Eyewitnesses say they saw the students being bundled into police cars after the police shot at buses carrying the students, killing three of them.
