Police are becoming "increasingly concerned" about a 43-year-old woman who has gone missing with her two small children.
Sian Blake, 43, went missing from Erith, Kent, with her children Zachary, eight, and Amon, four.
She was last seen on Sunday December 13 around Waltham Forest in east London, and police in Bexley, south east London, believe she is still in the London area.
The Metropolitan Police is now appealing to the public for help finding her.
A spokeswoman for the force said: "We are increasingly concerned about her and her children's wellbeing. We have exhausted all other lines of enquiry."
Ms Blake is described by police as a black woman, 5ft 2ins tall of slim build with short black hair. She wears glasses but does also wear contact lenses.
Anyone with any information is asked to call police on 101 or Missing People on 116000, quoting reference 15MIS050346.
