Police officers were called to Penygroes six hours before the body of Emma Louise Baum was discovered.

North Wales Police say officers initially failed to find the remains of the murdered mum-of-one because they could see nothing suspicious in the area.

The force has now referred itself to the Independent Police Complaints Commission, a spokeswoman has confirmed.

Officers were initially deployed in the vicinity of Emma's home at 34 Llwyndu Road shortly after 4am, after they received a report of a woman screaming.

The 22-year-old's body was eventually found at 10.45am at the house, where she lived with her two-year-old son.

“A further appeal is being made for witnesses to come forward.

“We are particularly keen to speak to anyone who has seen or heard anything suspicious in the Llwyndu Road area of Penygroes during the early hours of yesterday morning.

“As part of the investigation we would also appeal to anyone who has private CCTV systems to contact the major incident room on 101 quoting reference U105426.”

A spokeswoman added: "The investigation is ongoing and officers continue to provide a high visibility police presence in the village of Penygroes.

"If you have any information about this incident or if you have witnessed any suspicious behaviour at or near this location please contact Police on 101 or Crimestoppers anonymously on 0800 555 111 and quote U105426."

A spokesman for the IPCC said: “We have received a referral this afternoon from North Wales Police and are currently assessing it.”
