PM version: Teens abusing parents 'serious and often hidden issue'
Children and teenagers abusing their parents is a growing concern, charities and experts have told Newsbeat.
The group Family Lives says nearly a third of over 80,000 recent calls to its helpline involved children being physically aggressive.
A Home Office minister says it is "a serious and often hidden issue".
One academic has called it "a hidden form of violence against women", after finding that 9 out of 10 recorded victims were mothers.
