Police in Sheffield are appealing for the public's help to find 15-year-old Joshua - who is originally from Manchester.
He was last seen leaving his home in the Norton area of Sheffield at around midday on Friday, October 8.
He is white, and is described as being of medium build, being 5ft 7ins tall, with brown hair, brown eyes and a small mole under his right eye. He was wearing a dark navy tracksuit, a blue padded jacket and black Nike Air trainers.
Joshua speaks with a Mancunian accent, but he is also known to put on a Scottish accent when talking.
As well as Manchester, he is also known to frequent the Chesterfield area.
He is an avid football fan and is known to start conversations with strangers about the subject. He can sometimes lose his hearing during conversations, and will repeat the word ‘parrot’ when this happens.
"Officers are becoming increasingly concerned for Joshua's welfare and want to speak to anybody who has seen him," a statement from South Yorkshire Police said.
Can you help? Do you know where he might be? If you have any information which may help police enquiries, please call 101 quoting incident number 1143 of 8 October.
