LONDON — A photojournalist's tweet about the misuse of a photo he took of a Sudanese refugee wearing an "I love London" hoodie has been shared over 9,000 times on Twitter.

Captioned, "Three so-called 'child' migrants arrive in Croydon from the Calais camp," the photo appeared alongside two others for a story published online by British news organization the Telegraph. The article covers the Home Office's recent decision not to conduct dental checks to verify the age of refugee children arriving in the country.

However, according to photographer Björn Kietzmann, his image was taken in Calais, not in Croydon:

Dear @Telegraph colleagues the photo in the middle shows a refugee in Calais not in Croydon. I should know because I took it 2 days ago pic.twitter.com/bmozcgS5Qq — Björn Kietzmann (@bjokie) October 19, 2016

Kietzmann recently spent time documenting the plight of refugees and migrants living in the so-called 'Jungle' in Calais, the contentious camp in Northern France.

The photo in question is licensed by British photo agency Rex and includes a brief caption explaining that the man in the picture has lived in the Jungle for four months — and that the photo was taken in Calais.

In a Facebook post, Kietzmann further explains his frustration at the framing of his photo.

He writes, "As a journalist, I find it shocking how my material was taken out of context."

The Telegraph has since removed the photo of the Sudanese refugee.

Mashable spoke to Keitzmann via Facebook, who said that he believes the Telegraph should acknowledge the error.

He said, "If a newspaper doesn't want to lose credibility caused by a serious mistake, they should also be able to recognise [their] own mistakes.

"In my opinion the Telegraph should publish a clarification."

Mashable reached out to the Telegraph for a statement, and they responded that they did not wish to comment at this time.

The identity of the person featured to the right of Kietzmann's image has also been called into question amid speculation that the man is an interpreter or aid worker. His photograph is currently the lead image in the aforementioned Telegraph article, and has been published by other news organisations including The Sun.

TACT, a fostering and adoption charity in the UK, initially tweeted that they believed the man is an interpreter but has since deleted the tweet.

This clip suggests the 'child refugee' splashed across the front page of tomorrow's Sun is actually an interpreter. pic.twitter.com/ZBhYOPFcwz — Adam Bienkov (@AdamBienkov) October 19, 2016

@bjokie @mjwwales @Telegraph Another media outlet opines that the one on the right is an aid worker. I haven't fact checked. — Zoë Sumra (@ZoeSumra) October 19, 2016

TACT released a statement explaining that, while it believed its source to be credible, it did not wish "to cause any further distress to the individual depicted."

Metro reports that the Home Office has denied that the man worked as one of its employees, however, his identity has yet to be revealed. Mashable will update this story accordingly as more information becomes available.
