FORMER Peruvian president Olllanta Humala and his wife were jailed for 18 months without charge or trial on Thursday night.

Judge Richard Concepcion ordered Mr Humala and Nadine Heredia be taken into custody pending the results of a probe into corruption allegations.

He claimed preventative detention was “appropriate and necessary” as there was a “high probability” the pair would try to escape justice — despite surrendering their passports to the court on Wednesday.
