The CBI has arrested a Goa-based man for allegedly sexually abusing 25-30 children and selling videos of his illicit acts to Indians and foreigners through the dark web and social media platforms, officials said on Tuesday.

The accused, a 29-year-old chef in a hotel in Goa, was booked by the CBI on June 22, 2020 after the agency got leads about his activities during the probe against a Chitrakoot-based alleged paedophile who was an engineer in the Uttar Pradesh irrigation department, they said.
