Over 100 officers took part in the police operation launched early on Tuesday morning. The national police officers were acting on the orders of the anti-corruption prosecutor in Alicante and an Orihuela judge.
Their job was to detain Alicante provincial president José Joaquin Ripoll along with three councillors from Orihuela and several prominent local businessmen as part of an investigation linked to the awarding of lucrative rubbish collection contracts.
According to the ministry of the interior, those arrested have been charged with bribery, fraud, peddling of political favours and perverting the course of justice.
However, a press release sent out from the Regional Supreme Court in Valencia on Wednesday afternoon states that the judge investigating the case had not released an order for charges to be brought as yet.
Sr Ripoll maintains that he has not committed any crime.
