His family have said their son - the brother of the murdered Real IRA leader Alan Ryan - will have a "traditional republican family funeral", but stressed he "will not receive a military funeral". A volley of shots were fired into the air over Alan Ryan's coffin the morning of his funeral in September 2012.
Balaclava-clad men and women wearing paramilitary-style uniforms also accompanied Alan's hearse in an apparent show of strength.
Garda are planning a major security operation ahead of his brother's funeral, but it is expected to be more low key. The Ryan family has called for no retaliation for his murder.
