Police are concerned for the whereabouts of missing teenager Zahra Mathew-Evans.
The 16-year-old was last seen at her home in Angmering shortly before 2pm on Tuesday and is not believed to be in possession of a mobile phone.
She is described as white Asian, about 5′ 3″, with very long and straight black hair.
She was last seen wearing black leggings, a white short-sleeved crop top and open-toed white shoes with a four-inch heel.
Zahra is known to have links to Sussex, Essex, Cambridgeshire and Suffolk.
PC Heather Mackay, of the Sussex Police missing persons team, said: “We’re extremely concerned for Zahra given her age and vulnerability, and the fact that she does not have a phone in her possession.
“We’re appealing for anyone with any information on her whereabouts to contact us as soon as possible on email@example.com or call 101, quoting serial 925 of 16/02.”
