A police detective sergeant working on the investigation into Ian Watkins' child sex offences has been served with gross misconduct notices by the police watchdog.

Yesterday (November 26), the former singer of the now-defunct Welsh band pleaded guilty to 13 sexual offences, including two of attempting to rape a baby. Two female co-defendants, who cannot be named, also admitted to numerous child sex offences. Read the full story here and here.

In February, the Independent Police Complaints Commission (IPCC) launched an investigation into whether South Wales Police acted quickly enough after being tipped off about Watkins. In a new statement issued to NME today (November 27), the IPCC has given more details about the nature of the investigation, revealing that the case is centred around the actions of one officer, who is also being investigated in another case where it is alleged that he failed to act on an allegation that a 15-year-old girl had been raped.

The statement reads: "The IPCC investigation into whether or not South Wales Police failed to take appropriate and timely action in relation to information they were in receipt of in advance of Mr Watkins' subsequent arrest is ongoing. We are considering matters dating back to 2008.

"At this stage the investigation is focused on the actions of one officer, a detective sergeant who is also being investigated in another case where it is alleged he failed to act on an allegation that a 15-year-old girl had been raped. That remains ongoing.

"The detective sergeant has been served with gross misconduct notices advising him that his conduct is subject to investigation."

Earlier today (November 27), Watkins' ex girlfriend claimed she warned police repeatedly for four years that he had told her he was a paedophile, but was ignored.

Last night Chief Superintendent Tim Jones, head of South Wales Police's Professional Standards Department, told Wales Online: "South Wales Police will fully support the Independent Police Complaints Commission's independent investigation and are committed to responding promptly to its findings."
