Paul Muldoon, the husband of missing Marbella mum Rebecca, is behind bars for the second time in 15 days.

Muldoon is wanted by the British authorities for financial crime, and was picked up on a European Arrest Warrant last night.

He was arrested on January 1 on suspicion of domestic violence against Rebecca, but after she failed to show to press charges the following day, Paul Muldoon was released on January 3.

Rebecca went missing on January 2 and has not used her mobile or withdrawn cash, and did not take her passport.

A woman’s body was discovered on the beach on Sunday and police are waiting for final DNA tests before publicly identifying her.

Paul Muldoon was arrested last night and British authorities have requested his extradition.
