The parents of schoolgirl Shelley Pratt have said they are worried that something has happened to their daughter which s preventing her from coming home.
Shelley went missing from her Croydon home on November 8. She was last seen getting off a 196 bus in Portland Road, South Norwood. Today her mother and father spoke of their concern.
– Detective Chief Inspector Mark Dunne, Metropolitan Police
"It has now been three weeks since Shelley went missing and concerns for her safety are understandably increasing by the day.
"Shelley has had absolutely no contact with friends or family since her disappearance. It is possible that Shelley may be with someone, perhaps in a house or a flat.
"I am encouraging people, particularly Croydon residents, to be nosey neighbours and be extra vigilant as to the movements of any young people who are new to the area."
A picture of the missing teenager will be displayed on a big screen at Crystal Palace's Selhurst Park during this weekend's match against Brighton.
Officers will also be handing out leaflets in Croydon town centre this weekend.
Anyone with information about where Shelley is can call police on 020 8721 4906.
