Five men in El Salvador, including a police officer, were arrested Wednesday in connection with the killing of French filmmaker and photographer Christian Poveda last week, the country's attorney general's office said.
A sixth man who allegedly ordered the murder was already in prison, according to a statement from the agency, CNN reported.
Poveda, whose documentary La Vida Loca follows the lifestyle and violence of the Mara 18 street gang in El Salvador was found shot dead on September 2.
Of those arrested, four were members of the Mara 18 gang, and one was National Civil Police Officer Juan Napoleon, the attorney general's office said.
La Vida Loca is slated for wider international release this month. Find out more about the film on its official website.
