The family and friends of a British man who went missing on a stag weekend in Prague have promised to keep searching the streets of the Czech capital until they get news "good or bad".
Builder Karl Law (35) vanished after getting separated from his friends on a pub crawl three weeks ago. There have been several potential sightings of him, but none confirmed and he has not contacted anyone who knows him.
His brother Craig Law (30) said: "No news is good news, so we are thinking positively. We don't want to think of the worst and believe that Karl is alive and out there somewhere."
"Some of us will stay here for as long as it takes to get the answer to what has happened to Karl, good or bad."
A small rotating group of family and friends from Fareham, Hampshire, are taking turns to fly to Prague, travelling around the city and putting up thousands of posters with Karl's photograph and numbers to call for anyone who spots him.
Karl's employer is still paying some of his wages and friends are rallying round to fund the appeal campaign.
"I thought he was going off to another club"
The last person to see Karl was his cousin Steve Stock, wandering near Maxim's bar close to the centre of Prague's lively old town.
"We had split into two groups and I thought he was going off to another club or to get something to eat. Of course, we had all been drinking, but it was our second night and everybody seemed fine."
His family and friends are travelling the metro line, hopping on and off at each station to stick up posters.
They are also handing out appeal notices among tourists in the packed Christmas market.
They have also visited several homeless people living in makeshift shelters along the banks of the Vltava River.
Craig said: "It could be he has had an accident or banged his head somewhere and got disorientated. He could be confused and be sleeping rough."
The group has also been making regular checks at hospitals and homeless shelters. On the night he disappeared Karl did not have his mobile phone or passport with him.
The searchers believe he is still in Prague, a feeling fuelled by possible sightings of him in a cafe, getting off a number 14 tram, or even walking close to Maxim's.
Prague police said they were doing all they could to find him, but released a statement suggesting his family had not disclosed that he had "consumed both alcohol and narcotic drugs and psychotropic substances extensively during the few days before he disappeared".
