Police last night warned residents not to approach the man they believe gunned down a father of two in the street.
Officers have not recovered the weapon used to shoot dead 31-year-old scaffolder Xhem “Jim” Krasniqi in Church Street, Hove, on Saturday night.
Yesterday they named Edmund Nela as the man they believe killed the Albanian and shot at two of his relatives – and said he could still be armed.
They have also appealed for information about the whereabouts of Nela’s 34-year-old brother, Albert, who has also not been seen since the night of the shooting.
Detective Chief Inspector Jeff Riley said: “Xhem died of a single gunshot wound as he and his brother and nephew were shot at by a man they knew on Saturday evening.
“That man we believe was 30-year-old Edmund Nela.
“We have not recovered a gun so he could still have access to a firearm.”
The Nela brothers are of dual Albanian-British nationalities and have lived in Shoreham, Brighton and Hove for some years, although their addresses are uncertain.
Since Saturday police have raided five homes in the city and Shoreham and seized vehicles linked to the brothers.
However, they have not been seen and DCI Riley said police could not rule out the possibility they had fled the country.
He said it was highly unlikely they were still in Brighton and Hove.
DCI Riley said the brothers and Mr Krasniqi, who lived in Kent and was visiting his family in Brighton for the weekend, knew each other through the Albanian community.
He continued: “We believe the men all knew each other and we are open-minded as to the motive.
“The initial indication is that there's a personal dispute between some members of two families and this has escalated dramatically, leading to Xhem's tragic death.
“Prior to this incident police were not aware of any history between the individuals.”
Officers know very little about the Nela brothers.
Police do not know their occupations, details of their families or specific addresses where they have lived.
Patrols will be sent into the area near the shooting and visiting cafes that are known to be used by members of the Albanian community to try to find anyone who knows where the brothers are.
If you see either brother call police on 999 quoting Operation Welbeck or Crimestoppers anonymously on 0800 555111.
