A man has appeared in court charged with possessing a document likely to be of use to terrorists.
Seamus McGuigan, 39, of Gilpin Manor in Lurgan, was arrested after detectives searched his house on Wednesday.
A hand-written letter was found during the search which police say could have been used to interfere with another trial related to terrorism charges.
Mr McGuigan was remanded in custody. He is due to appear at Craigavon Crown Court next month via video-link.
