Sussex Police has launched an appeal to trace 17-year-old Ella Sears, who was reported missing from her home in Hove.
Officers said Ella was last seen in Hove on Wednesday, April 12, when she returned home briefly and left.
She is known to have contacts in both the Croydon area and in Brighton and Hove.
She is described as white, 5’5”, of slim or medium build, and has dark brown shoulder length hair. She was last seen wearing tight black jeans, and carrying a black back-pack.
Vicky Morris, Brighton and Hove missing persons co-ordinator, said: “We are obviously concerned for Ella because of her age.
“She’s not in any trouble but we do need her, or anyone who has seen her or who may know where she is, to get in touch as soon as possible so that we know she’s okay.”
Anyone able to help should contact police online, email email@example.com or phone 101 quoting serial 1207 of 11/4.
