A teenager who went missing from her home in Buckinghamshire may be in Glasgow, police have said.
The 15-year-old, called Samreen, left her home in High Wycombe on 2 January.
She was spotted boarding a train to Birmingham Moor Street and was last seen in Circus Drive, Glasgow, on Thursday.
Police said there was growing concern about her welfare. Her parents have urged her to get in touch and let them know she is safe.
Samreen is described as 5ft tall, of slim build, with very long dyed brown hair, brown eyes and she may be wearing glasses. She has two earring studs in each ear and a stud in the upper left ear.
She was last seen wearing blue jeans, a grey waist-length coat with brown buttons and black ankle boots.
Det Sgt Yasmin Dean, from Thames Valley Police, said: "We are increasingly worried about Samreen's welfare. Even with the help of friends, she must be running out of funds and means of support."
Her parents said: "We are really worried about you and we just want you to get in touch and let us know that you are safe.
"We love you lots and are missing you terribly."
