A man is wanted by police in connection with an investigation into a missing 15-year-old girl.

Thames Valley Police want to speak to Billy Ross, 19, of no fixed abode, in connection with an investigation being carried out to find Macey – whose surname was not given and was reported missing from Milton Keynes on Monday.

He is white, approximately 5ft 8ins tall, with brown eyes and brown hair.

Ross is known to frequent Essex, London, Sussex and Great Yarmouth, the force said. He is also known to travel by train.
