New CCTV images of a teenager taken less than an hour before she disappeared a week ago have been released by police.
Gaia Pope was staying at an address in Swanage, Dorset when she disappeared on the afternoon of November 7.
Less than an hour before her last confirmed sighting at 3.39pm, she was being driven between Langton Matravers and Swanage by a family member when they stopped off for fuel at St Michael's Garage on Valley Road in Swanage.
Dorset Police have released two CCTV images of the 19-year-old inside the garage buying an ice cream at around 2.55pm.
The last confirmed sighting of Gaia was at an address in Manor Gardens on Morrison Road in Swanage at about 4pm.
Forensic investigations are continuing at two properties in Manor Gardens, which are believed to be the homes of a 71-year-old woman and a 19-year-old man.
They were released under investigation on Tuesday after being arrested on suspicion of murder by police the previous day.
Detective Chief Inspector Neil Devoto, who is leading the investigation, said: "We believe Gaia was wearing the same grey and white woven leggings and white trainers, but was last seen in a red checked shirt with white buttons.
"When she disappeared she was not wearing the black jacket pictured, which was recovered at an address in Manor Gardens.
"Our search efforts are continuing and I would again appeal to the public that if they have any information, however small, that could lead us to finding Gaia, please get in touch.
"Finally, I would like to offer my thoughts to Gaia's family and friends in what is an incredibly difficult time for them.
"It has been over a week since she went missing and we are doing all we can in order to find her."
The search to find the teenager has continued with search teams focusing all their efforts inland in Swanage and the surrounding area, supported by Dorset search and rescue and specialist units from neighbouring police forces.
