Five CEOs from major tech companies have testified at a Senate hearing about the protection of children from online sexual exploitation.

We hear from a bereaved parent whose son fell victim to a sexual extortion scam.

Also in the programme: a young monarchy-reform activist in Thailand speaks about his political party potentially being dissolved; and the extraordinary story of three Irish siblings abandoned at birth who found each other through DNA, and now think they may have another brother.
