So-called paedophile hunter group Guardians of the North says its work "picked up quickly" as the coronavirus lockdown eased.
The controversial organisation's members pose as children online and arrange face-to-face meetings to snare potential child sex offenders.
Such vigilante groups have come under fire for running the risk of jeopardising court cases.
Since 2016, Guardians of the North said it has has helped secure more than 30 convictions in the North East.
The Home Office says while child protection matters greatly to people, they should not take the law into their own hands.
