Kilmar Abrego Garcia was severely beaten, deprived of sleep and subjected to psychological torture at an El Salvador mega-prison after he was wrongly deported from the US by the Trump administration,

At the notorious CECOT prison, he was forced to frog-march, had to kneel from 9 p.m. to 6 a.m. and was subjected to beatings and threats, his lawyers said Wednesday.

His mistaken deportation became a flashpoint in tensions over the Trump Administration’s hardline immigration policy.
