The Internet Watch Foundation has said that 2021 was the worst year on record for child sexual abuse online.

The online safety group has now called for more support for parents to help spot the danger.

The organisation finds and helps to remove abusive content from the internet. It said it investigated 361,000 reports of suspected criminal material in 2021 – more than it dealt with in its entire first 15 years of existence between 1996 and 2011.

It said lockdowns had an impact on the figures as more people, particularly schoolchildren, were spending more time online. This in turn has made them more vulnerable to cybercriminals.

In its research, the online safety group said it had seen a “three-fold” increase in self-generated imagery showing seven to 10-year-olds as they were increasingly targeted and groomed by internet predators “on an industrial scale”.

It said that self-generated material is often made using webcams in a child’s own bedroom and then shared online.

IWF chief executive, Susie Hargreaves, said it was vital parents were given more help to enable them to better spot and understand danger online and ultimately protect their children.

She said: “Children are being targeted, approached, groomed and abused by criminals on an industrial scale.

“So often, this sexual abuse is happening in children’s bedrooms in family homes, with parents being wholly unaware of what is being done to their children by strangers with an internet connection.

“Devices can be an open door into your home, and children can be especially vulnerable to being drawn into these predators’ traps.

“We know that if parents have one good conversation with their children it can make all the difference, and could be what stops a lifetime of hurt as a result of this grooming.

“Parents need to be supported in knowing how to broach the topic with their children, and to give them the confidence to call out inappropriate behaviour when they see it.

“We’re pleased to see the Government stepping in to help educate parents, and provide them with ways they can help protect children from this growing problem.”

The Government is set to launch a new campaign on Friday, January 14. It will include a new website called ‘Stop Abuse Together’, which will offer guidance to parents on how to spot signs of sexual abuse and how to keep them safe.

The latest IWF figures showed that of the 361,000 reports investigated in 2021, 252,000 were confirmed to be URLs containing images or videos of child sexual abuse.

These figures were also a 21% increase in the number of investigated reports compared to 2020.

Responding to the figures, the Chancellor of the Duchy of Lancaster, Steve Barclay, said: “The internet is a vital resource for children to learn and socialise with their peers, but this shocking data shows the unacceptable risks that children can face online.

“Our National Cyber Strategy aims to make the UK the safest place to live and work online; strengthening laws and working across Government, law enforcement and internet providers to fight malicious online activity.

“With the new Stop Abuse Together campaign, we will help empower millions of parents to spot the potential signs of child sexual abuse and take action to keep their children safe.

“All children have a right to be safe from the abhorrent crime of sexual abuse, and we all have a role to play in keeping them safe. Let’s stop abuse together.”
