A controversial Jersey politician who claimed officials on the island covered up child abuse is considering legal action against the police after he was arrested.
Whistle-blower Stuart Syvret was arrested in the parish of Grouville in connection with an alleged breach of data protection law.
The 43-year-old senator was not charged and, after a day in custody, was released "pending further inquiries".
He said officers searched his home and he was kept in a police cell all day other than for a two-hour interview. He claims the police did not have a warrant to search his property and believes the arrest was politically motivated.
Mr Syvret said: "The whole exercise was designed to intimidate and harass me and to intimidate the whistle-blowers who give me information. This was an act of oppression against the person who is leading the opposition to the establishment on this island.
"I am certainly going to seriously contemplate a legal action of my own because of this.
"This is what happens to anyone on Jersey who rocks the boat - you get clobbered."
Mr Syvret was an outspoken critic of the establishment's handling of the historic police investigation into child abuse on the island.
In 2007 he was dismissed from his post as Minister for Health and Social Services after claiming abuse cases were being covered up.
The investigation focussed on the Haut de la Garenne children's home, where hundreds of former residents claimed they were sexually and violently assaulted.
