Seven bodyguards have been arrested over their alleged involvement in the murder of a popular Mexican mayor, authorities have said.
Carlos Manzo, the mayor of Uruapan and an outspoken critic of cartel violence, was shot dead on 1 November at a public event marking the Day of the Dead.
The office of the attorney general of Michoacán state said in a brief statement that the public servants had been detained "for their probable participation in the crime of aggravated homicide, in commission by omission" in relation to Manzo's killing.
It follows the arrest on Wednesday of a man police described as the mastermind behind the murder, who officials said had links to a powerful cartel.
The attorney general's office in Michoacán, to the west of the capital, Mexico City, said the seven guards had been arrested by both state and federal officials, including the National Guard.
