Daily SumUp

Two ex-police officers have been arrested in Mexico for alleged links to a suspected drug cartel training ground where bones, shoes and clothing were found earlier this month, authorities said Sunday.

The discovery of human remains at what Human Rights Watch has called an "apparent mass killing site" has caused shock in a country where murders and kidnappings are daily occurrences.

One of the former officers is accused of kidnapping a man who was held at the Izaguirre Ranch in Teuchitlan in the western state of Jalisco, the state attorney general's office said in a statement.

The former agent and colleagues detained the victim for a supposed search as he was riding a motorbike, before handing him over to a group who took him to the site, it said.
