The entire police force of a western Mexican town has been detained on suspicion of involvement in the murder of a mayoral candidate.
All 28 members of the Ocampo police department were arrested Sunday in connection with the murder of Fernando Angeles Juarez.
Juarez was running for mayor of Ocampo, a town of about 20,000 people in Michoacan state, as a member of the center-left Party of the Democratic Revolution. He was shot dead Thursday.
He is the third mayoral candidate to be killed in Michoacan state this month.
State officials said in a statement Sunday the Ocampo police force had been arrested as part of a probe into potential violations of the police code of conduct.
More than 100 politicians and candidates have been killed in the run-up to Mexico's election on July 1 when voters will choose a new president and vote for hundreds of other candidates running for federal, state and municipal positions.
