Television presenter Petra Bagust and actor Ido Drent are off to Thailand and Cambodia for just over a week to get a first-hand understanding of the human-trafficking industry. They will be visiting Tearfund's local anti-trafficking partners who work to rescue and rehabilitate trafficking victims and prosecute offenders. They are sharing daily video diaries of their travels with the Herald.
On their second day in Southeast Asia, Petra Bagust and Ido Drent head to Chiang Mai in the north of Thailand.
Drent says the city is notorious for paedophiles operating in the area.
On their way to the city, both admitted to feeling overwhelmed by the sheer size of the human trafficking industry which Tearfund claims is rife in Southeast Asia.
Human trafficking is an organised criminal activity that uses deception, coercion and force to transport and harbour human beings for the purpose of exploitation.
