A body found by police in Prague has been confirmed as that of British builder Karl Law (35), who went missing on a stag weekend, sources say.

Police recovered the body from the freezing water near a city centre bridge at the weekend, close to where the he was last seen three weeks ago.

Mr Law became separated from his brother and friends on a pub crawl to celebrate a friend's forthcoming wedding.

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.

The family had been alerted by police after the discovery of the body, which was too decomposed to be readily identified.

It is believed the body had only underpants and there was no sign of the clothes Mr Law had been wearing when he vanished.

The absence of clothes might suggest Mr Law was the victim of a crime.

A small group of searchers, led by Mr Law's brother Craig, had put up thousands of posters and appealed for help all over the city.

The group had promised to stay in the Czech capital until there was news "good or bad".
