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.

Kilmar Abrego Garcia said he suffered severe beatings, severe sleep deprivation and psychological torture in the notorious El Salvador prison the Trump administration had deported him to in March, according to court documents filed Wednesday.

The 29-year-old is now detained in Tennessee after being returned to the US and is awaiting trial on human smuggling charges.
