The father of a missing 12-year-old boy from Plymouth is desperately appealing for his safe return and has told him, "I miss you mate."

Callem Down was last seen in the city on Bank Holiday Monday, 25 May.

Concerns are now growing for his safety, and Devon and Cornwall Police officers are searching for the youngster.

His father, Chris, has begged his son to let him or the police know he is safe.

Contact the police or me soon please little man. I miss you mate.

Callem was last seen wearing an orange and black cap with a KTM logo, a white Adidas t-shirt and grey bottoms with black Adidas trainers.

He was also carrying an Adidas black-over-the-shoulder bag.

The 12-year-old is a slim, white male with brown hair. He is about 4ft 6ins tall.

Plymouth neighbourhood team leader Sgt Roger Hocking tweeted a picture the missing boy and has asked anyone who knows anything to call 101.
