From BBC News:
A parliamentary candidate in Ynys Môn is being investigated by the Public Services Ombudsman for Wales after a complaint by North Wales Police.
Peter Rogers, an independent, is also a local councillor and represents Anglesey council on North Wales Police Authority.
The complaint follows an incident at Holyhead Police station when Mr Rogers accompanied a constituent.
Mr Rogers has confirmed that he has no plans to stand down as a candidate.
He has also threatened to make an official complaint of his own about the way the police were dealing with the matter.
Mr Rogers told BBC Wales: "I'm disappointed that this information has been leaked to the media at a time when I'm a candidate in the election.
"The ombudsman must be allowed to conduct his investigation without being hampered by politically motivated leaks."
A spokesperson for Anglesey council said: "We can confirm that a complaint has been made by North Wales Police regarding Councillor Peter Rogers and that the ombudsman is investigating the matter."
A spokesman for North Wales Police authority said: "We can confirm that a complaint is being considered by the ombudsman."
The ombudsman's office confirmed that they have received a complaint about Mr Rogers and are currently investigating.
Albert Owen, the Labour parliamentary candidate in the Ynys Môn constituency, said: "I don't know the details and have no comment to make"
John Wyn Jones, press officer for Plaid Cymru Ynys Môn, speaking on behalf of the party's parliamentary candidate Dylan Rees, said "Mr Rogers has proved to be a politician who is unable to work with other people, whether it be the Conservative party or his colleagues in local government.
"This isolation means that he is unable to deliver for the people he represents."
A Conservative party spokesman said: "This a matter for Mr Rogers, North Wales Police and the Public Services Ombudsman. It would not be appropriate to comment at this stage."
