CCTV footage of teenager Gaia Pope shortly before she went missing has been released by police.

Gaia, 19, who lives in Langton Matravers, was staying at an address in Swanage when she disappeared five days ago.

The footage shows Gaia running along Morrison Road at 3.39pm on Tuesday.

The last reported sighting of Gaia was at an address in Manor Gardens on Morrison Road, Swanage, at around 4pm on the same day.

Police believe she was wearing a red checked shirt with white buttons, grey and white woven leggings and white trainers.

The coastguard, NPAS helicopter and Dorset Search and Rescue have all been involved in the search, with police checking door to door, CCTV and stopping vehicles in the Swanage area.

Inspector Andy Edwards, of Purbeck police, said: “I am releasing this image in the hope that it might jog someone’s memory. If you recall seeing Gaia, or a woman matching the description given, please contact Dorset Police.

“Officers are continuing to search the Swanage area and are grateful to all our partner agencies and volunteer groups for their assistance.

“We are doing everything possible to try and locate Gaia. Our thoughts are with her family at what must be a very difficult time and we are doing everything we possibly can to support them.

“I would urge any members of the public who have information as to where Gaia could be to contact police immediately.

"We would also urge anyone who may have dashcam footage from their vehicles covering major routes in Swanage over the last three days to review it to see if there are any sightings of someone matching Gaia’s description.

“Finally, I would appeal to Gaia, to contact us or your family as we all want to ensure that you are safe and well.”

Hundreds of people have scoured areas of Bournemouth, Swanage and Poole in the hope of finding Gaia.

‘Missing person’ leaflets with Gaia’s picture on have also been taped to lamp-posts, pinned to noticeboards and left in shops and community halls around the county, and new images of the teenager have been shared on social media.

She has epilepsy, which causes her to suffer seizures, and it is not known if she has her medication with her.

She also does not have her phone with her.

Cousin Marienna Pope-Weidemann said Gaia’s epilepsy is “severe”.

“We have had absolutely no information about her since she went missing,” she said.

“Her condition is very severe, she usually has seizures every day and during the night.

“Sometimes they are small and perfectly manageable, sometimes we have to call the paramedics and she requires emergency hospital treatment.”

She thanked emergency services, members of the public who have joined the search and representatives from the Purbeck Gazette, who have printed 10,000 posters.

“Everyone has been absolutely amazing,” she said.

Appealing directly to Gaia to get in touch with her family, Marienna said: “Gaia, if you’re able to make contact with any of us or the police, please do it.

“We just desperately need to know that you are OK, that you are safe.”

Anyone with information about Gaia’s whereabouts is asked to call 101, quoting incident number 9:179.
