Search efforts are continuing as a man from Melksham remains missing.
Police say they are “very concerned” for the welfare of 19-year-old Christian.
He was last seen in the Bradford on Avon area on Tuesday afternoon (17 June).
It’s believed he may have travelled back towards his home address in Melksham.
Wiltshire Search and Rescue were tasked on Wednesday afternoon (18 June) and other specialist resources have now been deployed.
Hampshire Search and Rescue dogs and Avon and Somerset Police are both on scene providing assistance.
Christian is described as white, around 5ft 8ins tall, slim, with short brown hair.
He was wearing a blue baseball cap, grey waterproof jacket, blue t-shirt and blue jeans.
It’s understood that Christian went missing on Monday too, but was located on that occasion. He’s since disappeared again and searches are ongoing.
Officers are urging people not to approach Christian if they sight him, but instead call 999 quoting log 149 of 17 June.
