New age-progression images have been released of a boy who went missing when he was 14 years old.
Andrew Gosden vanished from near his Doncaster home in September 2007 and the mystery surrounding his disappearance has formed one of the most high-profile missing persons cases of the last two decades.
South Yorkshire Police said the new age-progression picture is the first to show Andrew, who would now be 26 years old, without glasses.
They have also released pictures of him with glasses and with shorter hair.
Detectives appealed to Andrew Gosden, or anyone who believes they may know him, to get in touch.
Andrew left his home in the Balby area of Doncaster on 14 December 2007 and was heading down Littlemoor Lane, towards Westfield Park, at around 8.30am.
About an hour later, he took out £200 from his bank account and boarded a London-bound train at Doncaster station.
The teenager was seen on CCTV at Kings Cross station in London at about 11.20am the same day.
A police spokesman said there have been many sightings of people bearing some resemblance to Andrew over the years, but no positive sighting has ever been confirmed.
Andrew’s father, Kevin, has released more details about his son on his blog, saying he has an “unusual” right ear, is deaf in his left ear, highly intelligent and speaks quickly and quietly without a strong accent.
When Andrew went missing, his eyesight was very bad and he needed strong lenses but one of the new pictures shows him without glasses as he may now wear contact lenses.
Detective Inspector Andy Knowles, who has overseen the investigation since 2017, said someone’s face can look “drastically different” without glasses so he hopes the picture will “jog someone’s memory”.
He said he hopes sharing specific features of Andrew’s appearance and character will reduce the number of “generalised sightings we receive”.
“We want you to study Kevin’s blog closely and think hard about anyone in your lives who may have one or more of these traits,” he said.
“Anyone in your life who has an incomplete life history, anyone who might not have easy access to a bank account or a passport possibly, with the distinctive right ear markings that we know Andrew had – we’d be really keen to speak to those people.”
Det Insp Knowles also appealed to Andrew, saying he can contact them “completely confidentially” so his family know he is safe.
Anyone who believes they have information about Andrew should contact South Yorkshire Police on 1010, quoting incident number 161 of 13 September 2017, or Crimestoppers anonymously on 0800 555111.
