And the number 18
The entire police force of the Mexican town of Ocampo has been detained on suspicion of involvement in the murder of a mayoral candidate.
Fernando Ángeles Juárez, 64, was shot dead by unknown gunmen on Thursday outside one of his properties.
More than 100 politicians have been killed across Mexico ahead of general elections on 1 July.
Mr Ángeles was the third politician to be killed in the western state of Michoacán in just over a week.
The town's 27 police officers and the local public security secretary were detained by federal forces in the early hours of Sunday.
