A Briton is thought to have keen kidnapped in Spain by men posing as police officers.
The parents of Merseyside man Francis Brennan, 25, have appealed for information about his disappearance last month.
Mr Brennan was last seen in Alicante on January 24 when he was stopped in a friend's car by several men who posed as officers. The Spanish authorities believe he was then taken against his will.
Mr Brennan fled the UK for Spain ahead of a sentencing date last October for an assault he committed in the Thames Valley area in 2012.
Detective Superintendent Richie Carr, from Merseyside Police, said: "We do however believe he has been taken against his will and we and his family are hopeful that someone in the criminal fraternity here in Merseyside has information that could help bring about the safe return of Francis."
