In Britain two sisters are missing after going out to play in a park in Manchester.

The 8 and 11-year-olds have not been seen since last night.

British police say they are in an early and critical stage of the investigation.

The girls’ mother reported them missing just after 8pm last night when she could not find them after they had gone to play in Whitworth Park near their home.

11-year-old Liana Boyd is 5-feet-2 inches tall and was wearing a brown cardigan and black leggings.

8-year-old Teigan was wearing denim shorts and a green top.

Detectives want to talk to anyone who might have seen them.

Chief Superintendent Rob Potts 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 need anyone who may have seen the girls call us as this would be vital to our inquiries” he added.
