A former adviser to an MP has been arrested after a recording device, believed to be a camera, was found in the toilets of his constituency office.

David McConaghie is also a member of the Free Presbyterian Church and a prominent spokesman for a religious foundation.

He had been an election agent for David Simpson, the DUP MP for Upper Bann.

His solicitor said: "Mr McConaghie has not been charged with any criminal offence."

Mr Simpson said: "The police are currently investigating issues pertaining to an individual brought to their attention by myself.

"I no longer employ this individual and he does not hold any office in the party. No further comment will be made on the matter."

Mr McConaghie was employed by the party, although he stopped his membership some time ago.

He had trained to become a minister within the Free Presbyterian Church, which was started by the Reverend Ian Paisley.

He had previously been a minister in the Elim Pentecostal Church.

The discovery of the recording device was reported to the police by Mr Simpson. The story emerged on Friday morning in the Belfast Telegraph.

Mr McConaghie has also been a member of the Independent Orange Order.

In a statement the police said: "On 25 September, police received a report of an incident at premises in the Thomas Street area of Portadown.

"A 47-year-old male was later arrested and has since been released on bail pending further inquiries."
