Stacey revisits a documentary she made in the Philippines in 2017, investigating Filipino mothers who sexually abuse children, often their own, in front of webcams in exchange for money. Stacey catches up with 'Mike', (not his real name), a US undercover special agent from Homeland Security Investigations (HSI) who conducts secret operations to arrest the mothers and rescue the children. Mike's voice has been disguised. You can watch the full documentary, ‘Stacey Dooley Investigates: Mums Selling Their Kids for Sex’ now on BBC iPlayer.
