A boy aged just eight was believed to be under threat from forced marriage, new figures reveal.
Nearly 40 children under 18 have been deemed to be at risk of forced marriage in West Yorkshire since June 2014.
But only five of the 51 forced marriage cases in the region have led to anyone being prosecuted.
Meanwhile, in the West Midlands, 19 of 31 investigations have resulted in no one being charged.
In most of these cases, a suspect was named but the victim did not support further action or no suspect was named by the victim.
Out of the 67 given a forced marriage protection order in West Yorkshire, the majority of the potential victims were female.
The youngest was aged nine.
