The Netherlands has been plunged into a debate about how to deal with violent psychiatric patients, after images of a tethered teenager appeared on Dutch TV.

The pictures were taken after a tip-off from a whistle-blower, who worked at the institution where the 18-year-old, known only as Brandon, is confined.

The pictures show him wearing a harness attached to a metal bracket on the wall by a thick leather strap.

The BBC's Chris Morris reports.
