A 33-year-old man remains in police custody.
On Thursday morning, six men appeared in court in Ballymena charged with the murder of Kevin McDaid.
All six, and another two, were also charged with the attempted murder of Damien Fleming who was critically injured in the same attack in the Heights estate in Coleraine on Sunday evening.
One further man was charged with affray. In total, nine men faced 20 charges.
The men, aged between 18 and 50, all denied any involvement in the murder and attempted murder.
The violence flared when a loyalist mob of up to 40 entered a Catholic area of the town after Rangers beat Celtic to the Scottish Premiership.
'Heart attack'
A detective inspector told the court that a preliminary post mortem examination showed Mr McDaid had suffered a broken nose and bruising to his back and that he had an enlarged heart and died as a result of a heart attack.
More than 30 armed riot police ringed over 70 loyalists who filled the public benches as the men appeared.
More police provided a human shield on the other side of the court around friends and family members of Mr McDaid, including one of his four sons.
The 30-minute hearing passed without incident after the district judge warned anyone shouting out would be removed and dealt with.
First into the dock, handcuffed to a prison guard, was Aaron Beech, 23, of Windyhill Park, Coleraine, charged with attempted murder of Damien Fleming and unlawful assault.
He was followed by David Craig Cochrane, 18, of Windyhill Park, also charged with the murder of Mr McDaid and attempted murder.
His father, David James Cochrane, 47, of Windyhill Park, followed him into the dock accused of causing an affray.
Frank Daly, 48, of Rosemary Place, Coleraine, was charged with murder, attempted murder, assault and aiding and abetting the assault of Mr McDaid's widow Evelyn.
Christopher McDowell, 33, of Glebe Avenue, Coleraine, was charged with murder and attempted murder as was Paul Newman, 40, of Grassmere Close, Coleraine.
Ivan McDowell, 42, of Lisnablagh Road, Coleraine, was charged with attempted murder.
John McGrath, 50, of Hawthorne Place, Coleraine, was charged with murder, attempted murder and assault as was John Thompson, 29, of Daneshill Road, Coleraine.
All the accused were remanded in custody to reappear at Coleraine Magistrates' Court by video link on June 8.
Political unity
Chief constable Sir Hugh Orde confirmed his officers are also investigating an assault on a Protestant man in Coleraine on Sunday and said all such investigations were thoroughly pursued by police.
First minister Peter Robinson said the sectarian attack that led to Mr McDaid's death showed how much work had yet to be done in Northern Ireland to end sectarianism.
He pledged the Executive would work to develop a shared society.
Deputy first minister Martin McGuinness said that he shared power in government with Mr Robinson despite the political differences of their republican and unionist parties.
He said that by working together they were leading by example, but he said others needed to join in the efforts to combat hate.
Mr McGuinness said Mr McDaid was killed simply because he was a Catholic, and the Sinn Fein representative appealed for political unity to help defeat what he said was deep-rooted sectarianism.
However, despite the public show of unity, Sinn Fein sources said it had concerns over comments made by DUP Culture Minister Gregory Campbell.
Mr Campbell condemned Mr McDaid's murder but he also said he had received a large volume of calls from constituents alleging attacks on the Protestant community in Coleraine over recent months.
In response to earlier criticism of his comments from the nationalist SDLP, the DUP minister said he condemned Mr McDaid's murder and appealed for anyone with information to help the police.
He blamed a small number of violent individuals for attacks on Protestant families.
However, a Sinn Fein spokesman said: "There are those who have failed to deliver the required political leadership."
Sinn Fein has also said it is to make a complaint to the Police Ombudsman over police handling of the events in Coleraine surrounding Mr McDaid's murder, though police have already defended their actions on the night.
