A 16-year-old girl has been reported missing from a care home in Ipswich.
The Metropolitan Police said Sayeeda Begum Chowdhury has been missing since July 2.
Officers have released a photograph of her and urged members of the public to help them trace her.
The teenager has connections with Redbridge borough in London but has been seen recently in the Islington area.
She was previously believed to be in the company of another girl, but is now thought to be on her own.
She has also stopped contacting her social worker and this has increased concern for her welfare, a Metropolitan Police spokesman said.
The 16-year-old is described as 5ft 2ins tall and of a slim build.
Anyone with information is asked to call the police non-emergency line 101 or Missing People on 116 000.
