No child in the UK should be locked down in their school because of the actions of unvetted migrants. Today, a primary school with children as young as five was forced into lockdown. Pupils were kept inside their classrooms while police cars came and went from the school grounds. Outside the gates, worried parents gathered, desperate for updates on their children's safety.

With little information from the authorities, mothers and fathers were left to speculate. Fear grew as word spread that a migrant - reportedly seen near the school - had been arrested 24 hours before while trespassing on a different school's property. He was already wanted by police for failing to appear in court.

Despite this, the man was released on bail after only a few hours in custody. That night, he was reportedly found sleeping rough in a local resident's garden.

Frustrated by the lack of police action, a group of five or six local men arrived in two vehicles. They told me they had taken matters into their own hands, spending the morning searching for the same individual, concerned that he might pose a continued risk.

While police claimed to have deployed a team to locate him, many parents expressed serious distrust. The message from every parent was the same: "We don't trust the police. They're not keeping our children safe. No one is taking this seriously."

And their concerns are not isolated.

According to a WSI report, over 1,500 schools across the UK are within walking distance of migrant hotels which house unvetted, undocumented adults - mainly men.

Although no crime was committed on the school grounds today, many believe it's only a matter of time. No parent should have to stand at the school gates fearing for their child's safety. And no child should be sitting in a classroom wondering why they're being picked up early under police supervision.
