Watch Richard Payne's report.
Police are appealing for information following the disappearance of a man from Bristol who has been missing for a week.
Mark Owen was reported missing on Thursday 29 July, after not being seen since Monday 26 July.
The 53-year-old is described as being 5ft 11ins tall, of a medium build with muscular shoulders, tanned skin and short dark hair.
He was last seen wearing grey work shorts and a dark top and has tattoos on both of his arms.
Gloucestershire Police say he is now thought to be in the Tidenham area in the Forest of Dean.
His family and friends spent the weekend searching for him and were at his home in Patchway to continue the search today, as his disappearance entered a second week.
His son Ollie Owen said: "He knows he's got his family and friends, he's got a lot of people who care about him. So, it's still very unusual, so we don't really know what's happened."
Addressing his father directly, he added: "Let us know you're there. We all care so much."
The builder's van remains outside his home after Mark swapped it for another vehicle before he disappeared last Monday - the day he went missing.
That vehicle was found three days later in the Tidenham area in the Forest of Dean.
Officers are now asking anyone who lives locally to keep an eye out for him.
Police have already used a helicopter, scuba divers, and search dogs without success.
Mark was said to be organising work and making plans, adding to the unexpectedness of his disappearance.
The mother of Mark's partner, Denise Barlow, said: "We'd just like to feel that he's alive.
"I don't think that wherever he is, if he's alive, he's gonna feel safe, because why do this sort of thing if you're feeling safe and comfortable in your own shoes, you wouldn't do this would you.
"But any news to say that, 'yea, he's alive'."
If you have any information on his whereabouts contact Gloucestershire Constabulary on 101 quoting incident 133 of 29 July or 999 if Mark is present at the time.
