Young sisters go missing while playing near home in Manchester Manchester police say Whitworth Park would have been busy when the girls disappeared, and asked for anyone with information to contact them. Police are becoming increasingly concerned after two young sisters disappeared after playing out in a park near their home in Manchester. A search is taking place for Liana Boyd, 11, and her sister Teigan, eight, who have not been seen since Sunday night. The sisters were last seen at about 8pm, when they went out to play in Whitworth Park, close to their home. A short time later, however, their mother went to the park and was unable to find them. She then called the police. The sisters are white with brown hair. Liana is about 1.57 metres (5ft 2in) tall. She was last seen wearing a brown cardigan, black top and black leggings while Teigan was wearing denim shorts and a green top. Chief Superintendent Rob Potts, of Greater Manchester police, said: "Clearly, the family is fraught with worry that these girls have spent the night away from home. We have launched a police investigation where we are pulling out all the stops to find them safe and well. We are in the early, critical stages of our inquiries and we would urge anyone with information to call us as soon as possible. Whitworth Park is surrounded by busy roads and last night's weather would have meant that the park was busy. We need anyone who may have seen the girls to call us as this would be vital to our inquiries. He added: "Anyone with information is asked to call police on 101 or call the independent charity Crimestoppers anonymously on 0800 555 111."
