The two girls who went missing from a social care home in Newquay have been spotted at London Paddington train station.
Trang Nguyen and Linh Hoang, who don't speak any English, disappeared - seemingly without a trace - on April 27.
An appeal to find the teens was launched shortly after they went missing, but no new information surfaced.
Now however CCTV has been found showing the pair getting off a train in London Paddington at 7.20pm on the day they disappeared.
Police are still appealing for anyone who may have information on the vulnerable girls whereabouts - including the Vietnamese community in London - to contact them.
If anyone knows of the current whereabouts of either Thi Trang Nguyen or Thi Linh Hoang, or has seen them since Saturday 27 April, please contact Devon and Cornwall Police on 101 or firstname.lastname@example.org quoting log number 1003 27 April.
