For the last 14 months, investigative journalists Dan Evans and Tom Latchem have been looking into the case for the independent publication Byline Times.

“The police [in Barcelona] have failed to properly get CCTV, they didn’t get the communications history Levi was using and they didn’t do anything properly,” the pair claim.

They say they have been looking into the possibility Levi might have been blackmailed and want the case to be looked at more thoroughly.

“This is an international case, which has fallen between gaps and the police don’t work together,” they say.

“The British police thought ‘well it happened in Barcelona, we can wash our hands of it’, and the police there have fluffed it.”

Mossos d’Esquadra – the Catalan Police – have told the BBC they are waiting to hear from the courts whether there will be another investigation, as cases are directed by a judge.
