UK PM orders sex abuse inquiry probe
The prime minister is appointing a "senior independent figure" to look into the way allegations of sexual abuse at north Wales children's homes in the 1970s and '80s were dealt with, BBC reported.
Victim Steve Messham has said that the Waterhouse inquiry of 2000 only covered a fraction of the alleged assaults.
Another of the homes' residents says it did not hear all of the abuse claims.
Earlier, Downing Street said it would investigate Mr Messham's claims of abuse by a 1980s Tory politician.
Mr Messham is to meet the Welsh secretary on Tuesday.
Speaking in Abu Dhabi, the prime minister added: "Child abuse is an absolutely hateful and abhorrent crime and these allegations are truly dreadful and they mustn't be left hanging in the air, so I'm taking action today.
"I'm going to be asking a senior independent figure to lead an urgent investigation into whether the original inquiry was properly constituted and properly did its job and to report urgently to the government."
Mr Cameron also urged anyone who knows anything about the allegations of abuse to contact police.
