Andrew Gosden: Two arrests made in investigation into missing boy, 14, last seen in King’s Cross in 2007

Detectives probing the disappearance of a teenage boy feared to have been sold into a sex gang when he went missing almost 15 years ago have made two arrests.

Andrew Gosden was just 14 when he vanished after he left his house in Doncaster, South Yorks, withdrew £200 and bought a one-way ticket to London.

The straight A* student was last seen on CCTV at King’s Cross in September 2007, but his reason for heading to the capital and his whereabouts since remain a mystery.

Now, detectives have arrested confirmed they arrested two men, assisted by officers from the Metropolitan Police, on Wednesday, December 8 last year.

South Yorkshire Police said a 45-year-old man was arrested on suspicion of kidnap, human trafficking and the possession of indecent images of children.

And a 38-year-old man was arrested on suspicion of kidnap and human trafficking.

Both have now been released under investigation while enquiries continue.

Andrew, who would be 28 now, disappeared on September 14, 2007.

He boarded a train from Doncaster to London, with CCTV cameras capturing him when he arrived at Kings Cross station.

That was the last known sighting of Andrew, and since then no information about his movements has been corroborated by police, despite a massive manhunt.

Senior investigating officer, Detective Inspector Andy Knowles, said: “Our priority at this time is supporting Andrew’s family while we work through this new line of enquiry in the investigation.

“We are in close contact with them and they ask that their privacy is respected as our investigation continues.

“We have made numerous appeals over the years to find out where Andrew is and what happened to him when he disappeared.

“I would encourage anyone with any information they have not yet reported to come forward.”

Over the years since his disappearance, Andrew’s family has campaigned hard to try to find what had happened to him.

A search was made of the River Thames at one stage Experts even drew up artists’ impressions of what he would look like as an adult to try to update the search.

His face has featured in campaigns all across the country as missing peoples charities have publicised his case everywhere from on milk cartons to buses.

On the 10th anniversary of his disappearance, father Kevin revealed the “mental torture” he would go through every day, not knowing what has happened to his beloved son.

He said: “It is a huge mental torture and my thoughts are different every day.

“Hope comes and goes but at the end of the day you can’t give up on your own kid.

“You do still hope that maybe someone somewhere will find out he’s alive, so you know he is OK.

“Equally there is the feeling that if they found identifiable remains, you would at least know where you were.”

Since Andrew’s disappearance, there have been dozens of unconfirmed sightings from across the UK.

The family believes the most plausible theory places him at Pizza Hut on Oxford Street on the day he went missing, and later in Covent Garden.

Andrew has been described by his family as a quiet, gentle and extremely intelligent boy who took part in the government’s Young, Gifted & Talented Programme.

The Gosden family - Kevin, Glenys, sister Charlotte, and Andrew - were about to sit down for dinner on the evening of Friday 14 September 2007.

Charlotte was in her room on her new laptop, while Andrew was thought to be in the converted cellar of the house, playing on his console.

But when the shout went out to come and eat, he didn’t emerge.

In Andrew’s bedroom, his family found his McAuley Catholic High School blazer and tie hanging neatly over the back of a chair. Later they discovered his shirt and trousers in the washing machine.

After a series of increasingly frantic phone calls, they learned he had not been to school that day.

No remains have ever been found and a scan of the bed of the River Thames revealed no body.
