Sexual abuse of children within families is disturbingly the most common form and the impact on victims is devastating, sometimes damaging them long into adulthood if they don't get the right support.
In April 2016, it is revealed that Celine attempted to kill Pete Buchanan (Kai Owen), who was thought to be a victim of serial killer Lindsey Butterfield (Sophie Austin).
