LONDON â New CCTV footage apparently shows the moments before former BBC journalist and development worker Jacky Sutton was found hanged in the toilets at an airport in Istanbul over the weekend. The clip seems to show her passing through the city's Ataturk airport shortly before her death. It remains unclear whether she died on Saturday or Sunday. See also: Former BBC journalist found dead at Istanbul airport Local media have reported that Sutton killed herself after she missed her flight to Erbil in Iraq and was upset as she didn't have enough money to purchase a new ticket. However, that version of events isn't believed by many of her colleagues. The CCTV clip was published on Yeni Akit, a Turkish news site. Sutton appears to be walking through various parts of the airport; in later parts of the clip, she's carrying an additional bag, suggesting she purchased something there.

She began her current role in June, following the death of her predecessor Ammar al-Shahbander, who died in a car bomb attack in Baghdad in May. Sutton had joined al-Shahbander's friends and family at a memorial service in London. Anthony Borden, executive director of the IWPR, has said he wants to see an "open and transparent" investigation into Sutton's death. "All of her friends and colleagues who knew her better than me find it impossible to understand. It doesn't accord with what anything anyone knows about her," he said. "There's a matter of boot laces â I'm not even sure the boots she was wearing even had laces. If she wasn't wearing laces, how did she kill herself using boot laces?" "I'm not going to say I knew what was in her heart and mind but she had a positive nature and outlook," he added. "She took her new role as a really solemn commitment following the trauma of Ammar's death." Sutton's brother Ian said "odd circumstances" surrounded her death, The Daily Mail reports. "She had too much to live for and too many people relying on her to simply quit." Have something to add to this story? Share it in the comments.
