The Easy Rider star also advocated surrounding the schools of ICE agents' kids

The actor Peter Fonda has told his Twitter followers that President Trump's 12-year-old son Barron should be ripped from his mother's arms and put 'in a cage with pedophiles' in an expletive-laden rant about the border crisis.

He also called for 90 million people to take to the streets in protest at the government's decision to criminally prosecute migrants who cross the US border illegally and separate them from their children.

The Easy Rider star, who has more than 46,000 followers, also said 'we should hack the system' and 'get the addresses of ICE agents' to 'surround their homes' and 'find out what schools their children go to and surround the schools'.

Branding President Trump a 'f****** monster', he added: 'We need to scare the f*** out of [border agents]! Need to make their children worry now'.

He earlier referred to presidential adviser Stephen Miller as a 'pedophile'.

Fonda also called Miller, who is Jewish, 'Goebbels' in an apparent reference to Nazi propagandist Joseph Goebbels, an extreme anti-Semite who strongly supported the Holocaust and who arranged the murder of his own children in 1945.

In previous tweets on Tuesday, he said that White House Press Secretary Sarah Sanders should be deported 'to Arkansas'.

He also said her children should be given to Stephen Miller.

Fonda said Secretary of Homeland Security Kristjen Nielsen, meanwhile, should be 'put in a cage and poked at by passersby' as well as 'pilloried in Lafayette Square naked and whipped by passersby while being filmed for posterity'.

It comes after it was revealed that Trump administration officials have been sending babies and other young children separated from their parents at the US-Mexico border to at least three 'tender age' shelters in South Texas.

Lawyers and medical providers who have visited the Rio Grande Valley shelters described play rooms of crying preschool-age children in crisis.

The government also plans to open a fourth shelter to house hundreds of young migrant children in Houston, where city leaders denounced the move Tuesday.

Since the White House announced its zero tolerance policy in early May, more than 2,300 children have been taken from their parents at the US-Mexico border, resulting in a new influx of young children requiring government care.

The government has faced withering critiques over images of some of the children in cages inside US Border Patrol processing stations.
