The mother of a British man who went missing on a stag weekend in Prague three weeks ago is flying to the Czech capital to help with the search.
Karl Law, a 34-year-old father-of-one from Fareham, Hampshire, disappeared on 15 November.
His mother Sue and her brother are joining Lee Cross, Karl's cousin and friends to help with the search.
On Sunday, supporters said police found a body in the River Vltava but it was not thought to be Mr Law.
Writing on their Facebook appeal page, they believed footwear and clothes from the body did not belong to Mr Law.
Mr Cross said Mrs Law "just wanted to get over there" to help with the search.
Since his disappearance, Mr Law's family has been running a search campaign in the city and hired a private investigator.
Fund raising events have been held to pay for search efforts.
Mr Cross said Mrs Law was being supported by friends and family and wanted to add to the "feet on the ground".
Earlier this week, detectives in Prague said there had been "no fundamental shift" in the search for Mr Law.
Two sightings of Mr Law, on 16 November at the Palacky Square and the following day in the area of the National Theatre, were confirmed by police last week.
Prague police spokesman Tomas Hulan said: "In both of the cases he allegedly showed signs of intoxication of alcohol and some confusion."
