Nicolás Maduro has baptised his political crackdown Operación Tun Tun (Operation Knock Knock) after the spine-chilling visits his security forces pay their targets. But when members of Venezuela’s secret police came for Aixa Daniela Boada López, they announced their arrival with a thump not a tap.
“It was about half past midnight when we heard this loud bang on the roof,” said one witness to her detention in the industrial complex of Ciudad Guayana early on 1 August.
