His arrest came to light after another States member sent Deputy Curgenven an email asking him questions about the incident, and Home Affairs president Marc Leadbeater then posted the email on social media.
After being approached by the Guernsey Press, Deputy Curgenven provided a statement.
‘It is not my usual practice to comment publicly on matters concerning my private life. However, in light of recent speculation, I wish to clarify the position,’ said Deputy Curgenven.
‘I was arrested last week following an allegation made against me. I co-operated fully with the police throughout their investigation.
‘The police have confirmed that no further action will be taken and I was released without charge or caution. I categorically deny the allegation. I do not intend to comment further on this matter and will continue to focus on the work I was elected to do.’
After being advised of Deputy Leadbeater’s post on social media and Deputy Curgenven’s statement, the police issued a statement of their own.
‘On Sunday 18 October, officers arrested a man during the course of an inquiry,’ said a police spokesman.
‘That investigation has now been closed and no further action will be taken.’
The original questions emailed to Deputy Curgenven were asked by Deputy Jayne Ozanne following exchanges between deputies on various other matters. Deputy Leadbeater said he posted the questions on social media ‘for full transparency’ after Deputy Curgenven published some of the other exchanges.
Deputy Ozanne’s email to Deputy Curgenven included questions about whether he was arrested, the nature of the suspected offence and how long he was held by police.
In the States on Wednesday, Deputy Curgenven successfully proposed a motion to debate the annual report from the Police Complaints Commission, and Deputy Ozanne’s email also asked him to reflect on whether it had been appropriate to pursue that proposal three days after his arrest.
Deputy Curgenven was elected to the States at his first attempt in 2025. He has been a prominent campaigner for police reform.
In 2021, police responded to reports of a domestic incident at a house owned by Mr Curgenven which he shared with his girlfriend, to whom he is now married, and he was arrested and charged with assault, but this was dropped a few days later for lack of evidence.
In 2024, he and his wife won a high-profile claim for damages totalling about £12,000, which was settled when police officers agreed a deal with them, after the States and its insurers had paid the officers’ legal bills estimated at between £250,000 and £400,00 over a two-year period.
Deputy Curgenven has publicly praised reforms being led by police chief Damian Kitchen, who took over the force two years ago.
Deputies Curgenven and Leadbeater have repeatedly clashed inside and outside the Assembly. Earlier this year, Deputy Curgenven submitted a code of conduct complaint against Deputy Leadbeater which remains outstanding, and Deputy Curgenven was thrown off a group chaired by Deputy Leadbeater which is involved in changes to police complaints procedures.
