Mexico City Mayor Miguel Angel Mancera has expressed his outrage over the murder of photo journalist Ruben Espinosa and four women in the city last week. Their bodies were found in Mr Espinosa’s flat on Friday. They all had bullet wounds to the head.

Mr Espinosa, 31, worked for the investigative magazine Proceso. He had recently moved to Mexico City from the eastern state of Veracruz where he said he had been threatened and harassed. The photojournalist covered social movements in the city of Xalapa in Veracruz.He left the state for Mexico City after telling friends he had been followed and intimidated.

Veracruz is considered one of the most dangerous Mexican states for journalists – 17 have been killed there since 2000, rights group Article 19 says. Mayor Mancera said that there would be “no impunity in this matter”. “No line of investigation will be discarded,'” he told reporters at a news conference on yesterday.
