The British crime-fighting charity Crimestoppers and the Serious Organised Crime Agency made the appeal at a press conference in the southern city of Malaga in which they added 10 new names to their existing list of 17 suspects believed to on the run in Spain.
The 27 include drug draffickers, child abusers, rapists and murderers.
“These appeals include some very nasty individuals and crimes, and we need you, the public, to help us put them behind bars where they belong,” Dave Cording, Crimestoppers’ director of operations, told the news conference.
Since Crimestoppers began its Operation Captura in Spain in 2006, 23 of the 40 suspects on the list have been captured.
“The public response to the campaign so far has gone way beyond our expectations in locating criminals and we hope that this continues with the latest batch of appeals,” said Lord Ashcroft, who founded Crimestoppers in Britain in 1988.
Pictures and details of the suspects are available online at www.crimestoppers-uk.org.
An estimated one million Britons live in Spain, mostly along the Mediterranean coasts, while millions more travel to the country every year on holiday.
