Joseph was last seen yesterday (April 18) around 4pm when he left his home in the Colton area of Leeds on a bike.
Officers say they are becoming increasingly concerned about Joseph’s whereabouts as his disappearance is out of character and he has not been missing before.
Joseph is described as a white male, 5ft 8” in height, slim build with brown short hair. When he was last seen he was wearing navy blue Nike jogging bottoms, a blue Garforth Academy top and blue Adidas ‘Samba’ trainers.
Detective Inspector Phil Jackson, from North East Leeds CID, said: “Joseph is a popular and likeable young man whose family are understandably concerned by his sudden disappearance.
“If Joseph hears this appeal I would ask him to get in touch with us just so we know that you’re safe and well.”
Anyone with information is asked to contact North East Leeds CID at Stainbeck Police Station via: 101.
