Five men have appeared in court accused of causing grievous bodily harm with intent.
Among the defendants are three brothers, 29-year-old Kevin O’Kane, 26-year-old Stephen O’Kane and 24-year-old Mark O’Kane, all of Fanad Drive in Creggan.
Two other brothers also appeared in court. They are 25-year-old Gavin Fisher, of Sevenoaks, and 21-year-old Ciaran Fisher, of Swilly Gardens.
They are all jointly charged with causing grievous bodily harm to Mark McCallion on June 28.
They are further charged with making an affray.
The charges relate to an alleged incident in the Waterloo Street area of the city.
Kevin O’Kane faces two further charges of making a threat to kill on July 1.
An investigating officer told Derry Magistrates Court he believed he could connect all of the defendants to the charges.
He accepted the alleged injured party, Mr McCallion, has not made a statement of complaint and has not given consent for police to gather evidence about the alleged injuries.
The investigating officer said that, at this stage, the evidence against the accused was based on hearsay.
However, he added that Mr McCallion had given an interview to the local press and may change his mind.
The officer also revealed that the alleged incident was captured on CCTV and there were a ‘large number of people involved’.
He said police have appealed for witnesses to come forward.
Defence solicitor Paddy McGurk said there would be no bail applications for the five defendants at this time.
He told the court that it was ‘conceded addresses outside the city would be a pre-requisite’.
All five defendants were remanded in custody to appear in court again via video link on July 9.
There was a heavy police presence both inside and outside Bishop Street Courthouse during the brief hearing.
