A 21-year-old County Antrim man has been remanded in custody charged with having downloaded an article on how to make an explosive device.
Paul Edward Darragh of Craignamaddy Heights, Cargan, was charged with possession of an article for use in terrorism.
Ballymena Magistrates Court heard he allegedly committed the offence on Sunday.
A detective constable told the court the accused replied "no" when charged.
The officer said he believed he could connect Mr Darragh to the charge.
A defence solicitor asked the investigating officer if it was correct that Mr Darragh said he obtained the information from a website "out of curiosity" and the officer said that was correct.
The solicitor also said the details were "crude in the extreme" and that his client had consistently denied any connection to republican groups during interview.
