Concern is growing for the welfare of a missing teenage girl from Ealing .
Daria Pietrzak, 15, was last seen on Monday (April 4) in the Greenford area, at about 4.30pm.
Police said officers were growing "increasingly concerned" for the teenager's welfare and urged her to get in touch as they renewed their appeal on Thursday (April 7).
Daria is described as white, of slim build with shoulder length hair. It is not known what she is wearing.
Police believe she remains in London and is likely to be travelling on the transport network.
Anyone who has seen Daria or has any information about her whereabouts is asked to call officers at Ealing police via 101, or the charity Missing People on 116 000.
Police have also appealed for help to find Westminster PC Gordon Semple , who went missing last Friday (April 1).
