Migrants claiming to be minors spent the night out in the open after the demolishing of the 'Jungle' camp.
Those left were seen wrapping themselves in blankets as they prepared to sleep rough.
Police were seen patrolling the outskirts of what was France's biggest migrant camp.
Now there are fears a 'new Jungle' camp could soon pop up.
Some of those who were left were offered shelter in a church and a school.
Volunteers from Help Refugees said they were taking food and blankets to the stranded group, around half of whom are thought to be children.
