Police 'working hard' as slavery numbers in Wales doubles

The number of slavery victims in Wales has doubled in two years, with police saying they are training more officers to deal with the problem.

Last year 70 people were officially identified by police as victims - up from 35 in 2012.

Modern slaves are often vulnerable people being forced to illegally work against their will.

Wales' first anti-slavery week is being held to highlight the problem.

Det Supt Paul Griffiths is the operational policing lead on modern slavery for Wales.
