A vulnerable Thamesmead 15-year-old girl who went missing two weeks ago has links to Greenwich, Bromley, Croydon and Lewisham, police say.

Brittney Riggan was last seen leaving her home on October 27 at about 1.30pm but has since failed to return home.

She is a light-skinned black girl, approximately 5ft 11in, of large build, and is believed to have recently dyed part of her hair red, and had one side of her hair cut in a short distinctive style.

Although Brittney has been reported missing before, officers are becoming increasingly concerned over her welfare and are urging anybody with information on her whereabouts to get in touch with them.

Brittney has links to the Greenwich, Bromley and Croydon boroughs and officers also believe she may be in the Lewisham, Deptford or New Cross areas.

PC Rhianne Trill, from Greenwich's missing persons unit, said: "Brittney is a vulnerable young girl and while she has gone missing before, we are concerned about her safety given the amount of time she has been away now.

"She is not in any trouble and I would urge her friends or anyone who may know where she is to get in touch so that we can make sure she is safe and well."

Anyone with information on Brittney's whereabouts should call the police on 101 or contact the Missing People charity on 116000.
