Inside the 'world's most dangerous' hospital

A hospital in Guatemala has been described by campaigners as the world's most abusive and dangerous mental health institution. Former patients say they were raped while sedated, and the director himself admits - while being filmed undercover by the BBC - that patients are still being sexually abused.

In 2012, Guatemala was ordered by an American Human Rights Commission to make emergency improvements to the Federico Mora Hospital to "save lives". The government promised to comply. But an undercover BBC investigation found little has changed.

The government defends conditions in the hospital, says it has begun improving mental health care in the country and has ordered an investigation into sexual abuse claims.

This report by Chris Rogers contains some disturbing images.
