Child sexual exploitation has risen by almost half across London and more than doubled online, according to new statistics.

Figures released by the Metropolitan Police show that, between 2014 and 2016 there was a 49 per cent increase in crimes connected with child sexual exploitation (CSE) in London, rising from 618 to 922.

Cases of young people being groomed and abused online have increased by 135 per cent between 2015 and 2016.

There was also a 42 per cent increase in the number of children who police believe are at risk of CSE, from 1,116 to 1,582.

The Met Police lead on safeguarding, Assistant Commissioner Martin Hewitt, said; “In 2015, the Government declared CSE a ‘national threat’.

“These figures are a reflection of the scale of the challenge we are facing, and an indication that more victims are finding the confidence to come forward and report sexual abuse to police, knowing that we will take their allegations seriously.

“CSE is a hidden and under-reported crime, and I want to reiterate my plea today for victims to come forward. We have specially trained detectives who will help and support you.

“Often young people may not be aware that they are victims of CSE. My message to the wider public is, if you know someone who you suspect of being a victim or a perpetrator, please contact police.”

The Deputy Mayor for policing and crime, Sophie Linden, said: “The rise in the number of young Londoners for whom the threat of abuse and exploitation is a tragic reality is deeply concerning.

“The Mayor and I have made tackling this problem and supporting victims one of our top priorities.

“Together with the Met Police and our partner agencies, we are driving improvements in our ability to identify and safeguard those children who are at risk, and provide the support survivors need to move on from their experience. But it is a tough challenge.

“These crimes too often go unreported and remain hidden. I encourage anyone who has been a victim to report it to the police.

“There is help available and those responsible can be brought to justice, helping to make London a safe place for everyone.”

The statistics were released ahead of National CSE Awareness Day on Saturday, March 18.
