asked the Minister for Defence the cause of arrest and detention of Edward O'Callaghan, of 28 North Main Street, Cork; whether he is aware this gentleman had only just returned from the United States when arrested, and if his case is one of mistaken identity.

Mr. O'Callaghan was arrested on information which it is not in the public interest to disclose. I am aware that he had just returned from the United States. It is not a case of mistaken identity.
