A nursery worker has admitted sexually abusing young children in his care in north London.

Vincent Chan, 45, appeared at Wood Green Crown Court where he pleaded guilty to 26 charges including sexual assault by penetration, sexual assault by touching and making indecent images depicting the most severe category of child sex abuse.

The investigation into Chan followed a tip-off from a whistleblower and became one of the most “harrowing and complex” cases undertaken by the Metropolitan Police, the force said.

Chan, of Stanhope Avenue in Finchley, will be sentenced on 23 January.

Det Supt Lewis Basford, who led the Met Police’s investigation, said the offences had caused “deep shock and distress”.

The force said it was one of the most complex and disturbing cases that officers had investigated.

Chan started work at the nursery in 2017 and took on a number of roles including art specialist, room leader and nursery nurse.

He was entrusted with the care of children aged between two and four.

He first came to attention for filming the children in his care and overlaying the video with audio, according to the Met.
