Man admits 164 online child sex offences

A man has admitted carrying out 164 online sex offences against more than 130 children.

Derbyshire Police said Siah Riley was initially arrested in 2023 over child sex offences against two victims, but after his devices were seized officers uncovered "a huge catalogue of material" relating to at least 132 victims.

The 35-year-old, of Walbrook Road in Derby, pleaded guilty to 144 new offences when appearing at Derby Crown Court on Wednesday, having already admitted 20 child sex offences at two separate hearings in February and April last year.

He is due to be sentenced on 7 May.

Police said the new offences consisted of 117 counts of causing or inciting a child to engage in sexual activity, 22 counts of blackmail and five of engaging in sexual communication with a child.
