A 19-year-old Mexican man has died while being held in detention by US Immigration and Customs Enforcement (ICE), the agency has confirmed.

Royer Perez-Jimenez was found "unconscious and unresponsive" on Monday at the Glades County Detention Center in Florida, according to a statement from ICE.

"He died of a presumed suicide; however, the official cause of his death remains under investigation," the statement adds.

According to US media, Perez-Jimenez is the youngest prisoner to die in ICE custody since Donald Trump returned to office and launched a nationwide immigration crackdown.

Perez-Jimenez was found in his cell at 02:34 (07:34 GMT) on 16 March, according to ICE, which added that prison staff "immediately" began life-saving efforts.
