Police searching for missing teenager Gaia Pope have arrested a 49-year-old man on suspicion of murder.
The suspect is from the Swanage area and is believed to be known to the 19-year-old, Detective Superintendent Paul Kessel said on Thursday.
Earlier police found clothing similar to that worn by Miss Pope when she disappeared, following a tip-off from a member of the public.
It was discovered at 10.28am on an area of open land north of the coastal path near Swanage.
The owner of the clothes has not been identified but Miss Pope’s family have been informed, Dorset Police said.
Dorset Police have been carrying out forensic examinations of two properties in the Swanage area, as well as searches of land around the town.
The force released two CCTV images of the teenager taken inside St Michael’s Garage in Swanage when she bought an ice cream.
Gaia was being driven between Langton Matravers and Swanage by a family member when they stopped off for fuel 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.
The black jacket Gaia was wearing in the CCTV images was recovered from an address in Manor Gardens. Three vehicles have been seized.
