Lexi, 13, was last seen at the York Designer Outlet on Saturday afternoon.
Police say she was expected back at her home in Hambleton at 7pm that evening, but did not turn up.

“As part of our enquiries, we’re asking for anyone who has seen her or knows where she is to contact us immediately,” the spokesperson said.
“Please call us on 101 and pass information to our Force Control Room if you have seen her or please dial 999 if you have an immediate sighting.
