The NSPCC has joined forces with Hackney Council and the City and Hackney Safeguarding Children Board to help tackle child exploitation.

The organisations have launched a campaign encouraging residents to look out for the signs that a young person is being exploited and to report their concerns.

Signs include: “I don’t know how they’re affording all these new things,” “They’re always online and have become more secretive about what they’re doing,” and: “They’ve been going missing overnight and skipping school – I don’t know where they go”.

Cllr Anntoinette Bramble, cabinet member for children’s services, said: “The welfare of children and young people is our absolute priority, but unfortunately there are some people who seek to exploit them.

“There are lots of reasons why a child or young person might start acting differently, but a change in behaviour could be a sign that they’re at risk. By working in partnership with the NSPCC, we’re opening up another way for people to get advice and report anything they’re concerned about. Together we can all play a part in keeping young people safe.”

A poster and leaflet detail some of the signals that a child might be a victim of sexual exploitation or being targeted by gangs or extremists.

Anyone worried can call the NSPCC helpline on 0808 800 5000 or email help@nspcc.org.uk for advice.
