Detectives say they are "increasingly concerned" about the wellbeing of a schoolgirl missing for the past 11 days.
Jade Lynch, 14, disappeared during a shopping trip with her younger brothers in St Helens, Merseyside.
She said she was going to meet a friend, but hasn't been heard from since.
Jade, who lives in Warrington but had recently been living in St Helens, was last seen at 1pm on Saturday 26 March.
Det Supt John Betts of Cheshire Police said: "The biggest area of concern is that Jade has dropped out of contact with all her support network.
"Usually with a missing person inquiry the person stays in contact with somebody, certainly a 14-year-old. The fact she isn’t making contact with anybody is concerning."
