The Trump administration this week continued digging in on its claim that symbols tattooed on the fingers of Kilmar Abrego Garcia – a cross, a skull, a smiley face and a marijuana leaf – are proof that the man they wrongly deported to El Salvador is a member of MS-13.

BBC Verify looks at the evidence behind allegations that the Salvadoran mistakenly deported to a mega-prison was a dangerous gang member.

Experts are divided over whether knuckle tattoos highlighted by President Trump suggest the wrongly deported man may be associated with MS-13.
