THE whole police force in the Mexican town of Ocampo where a mayoral candidate was slain last week has been detained for an internal investigation, authorities said Sunday.

“All of them are being interviewed to proceed as due under law in the event anyone has taken part in acts that violate the town’s codes,” said the security secretariat in Michoacan state, where the town of about 20,000 people is located.

It did not give the exact number of police detained.

Mayoral candidate Fernando Angeles was shot dead last Thursday when he was preparing for campaign events.

The police have been transferred to the internal affairs unit of the state security secretariat, which did not clarify in its statement if the arrest is related to Angeles’ killing.

On Wednesday, Omar Gomez, an independent candidate for mayor of Aguililla, also in Michoacan, was shot to death.

On June 14, a candidate for mayor of Taretan in the same state, was killed. (SD-Agencies)
