There have been angry scenes at Londonderry Magistrates' Court as two brothers appeared charged with the murder of a man who was stabbed to death.

Karol Kelly, 35, was attacked during a fight involving a group of men in Grafton Street, Rosemount, at about 02:40 GMT on Sunday.

He was the father of five children.

Sean Anderson, 19, and Gary Anderson, 20, of Grafton Street, were remanded in custody on Wednesday.

Both men spoke only to confirm that they understood the charge and to confirm their names and dates of birth.

About 20 police officers were in court prior to their appearance and the hearing was temporarily delayed to allow for the arrival of police reinforcements.

Extra officers were called to the courtroom as friends of the victim and relatives and friends of the two defendants faced each other during the brief hearing.

One man carrying a photograph of the deceased was removed from the court.

Two other men were arrested for contempt of court.

Before the defendants appeared in court, District Judge Barney McElholm said he wanted to make "something very, very clear to the members of the public".

"A man is dead here," he said. "I realise tensions are running high, but I will not tolerate bad behaviour by any party.

"This is a necessary part of the court process and it will be conducted in a dignified manner. Anyone who does not do that risks an immediate prison sentence.

"I do not want this turning into a circus."

An investigating detective told the court she could connect the defendants to the murder charge.

Under questioning from solicitor Kevin Casey, who represents both defendants, the police witness confirmed that PSNI enquiries had revealed the deceased had made a number of threats towards the defendants.

The detective inspector also confirmed that enquiries revealed that shortly before the incident that led to the brothers being charged, the deceased and another man, who is not before the court, had entered the family home of the two defendants and assaulted them.

The detective inspector said the defendant Gary Anderson had lost parts of two of his teeth as a result of being assaulted.

The officer also confirmed to the court that another male, who was along with Mr Kelly and who is not before the court, was arrested on suspicion of burglary with intent to cause GBH.

The detective also accepted that Mr Kelly made a threat to kill anyone who went to the police.

There was no application for bail.

The defendants will appear in court again via video link on 29 March.

Meanwhile the two men who were arrested in the courtroom later apologised to the judge for their behaviour.

The court was told that one of the men arrested was a best friend of Mr Kelly and was a first aider who had given Mr Kelly CPR at the scene.

The court was told that the man has neither slept nor eaten since the incident.

The second man said he accepted he had not behaved in a dignified manner and said he was caught up by the tension and emotion in court.

Mr McElholm said the problem with crowd dynamics was once one person started, everybody else fell in behind.

He said he accepted the apologies of both men and told them they were they free to go.

A 17-year-old male who was arrested in Derry on Tuesday in connection to Mr Kelly's death has been charged with murder. He is due to appear in court on Thursday.
