An ex-detective who helped Jay Slater's family when the 19-year-old went missing in Tenerife has claimed that the Spanish police ignored a key piece of evidence.
Mark Williams-Thomas has accused Spanish authorities of failing to investigate an audio recording he offered to share which may have shed light on the British teenager's disappearance.
In a shocking six-minute long video posted on X/Twitter on Friday, Mr Williams-Thomas revealed the alleged difficulties he faced when dealing with the police in Tenerife.
'I sent the information I had in an email to Spanish authorities.' the ex-detective said.
'I told them I wasn't able to share the audio recording at this point because I needed to explain to them how I had obtained it and also I was very conscious that it was highly sensitive and I didn't want it just being shared all around.
