The people in charge wanted state-run news agency Notimex to become the “BBC of Mexico”. And after President Andres Manuel Lopez Obrador was elected in 2018, he appointed people who took on that mission. But now the agency has been rocked by allegations that it targeted online abuse at former employees and critical independent journalists.

An investigation by three organisations alleges that people among the most senior Notimex executives orchestrated the use of fake accounts to attack people they didn’t like. We find out how the trolling campaigns worked, speak to people who have been at the receiving end of the messages, and even talk to someone who admits they were told to carry out orders from the top.
