The family of a man, killed in a shooting in Hove, have described him as "a loving and devoted family man". Xhem Krasniqi was shot on Saturday evening.
Police took the unusual step of naming the men they wish to speak to in connection with his death yesterday. Officers say Edmund and Albert Nela were living in Brighton - but may well have left the Sussex area.
Video shows the victim and the two men being sought by police.
Detectives investigating the fatal shooting of Xhem Krasniqi have identified the men they want to trace after his murder. Xhem, 31, died of a single gun shot wound as he and his brother and nephew were shot at by a man they knew in Church Road, Hove, on Saturday evening.
Sussex Police: "That man we believe was 30-year-old Edmund Nela, a local man. We believe the men all knew each other and we are open-minded as to motive. Initial indication is that there's a personal dispute between members of two families and this has escalated, leading to Xhem's tragic death.
"Prior to this incident police were not aware of any history between the individuals. We are also seeking Edmund's brother Albert, 34, who also lives in the Brighton area. Neither of them has been seen since Saturday night."
Sussex Police have sought to reassure residents after a 31-year-old Kent man was killed in Hove.
Officers say that two other men were also injured in the shooting on Saturday night.
Residents should not feel at risk following last night's fatal shooting. I'm confident that this was an isolated incident and not a random attack.
Witnesses saw a horrific and tragic incident. A group of three men were shot at with what is believed to be a handgun and one of them was tragically killed.
This is not gang-related and as far as I am aware not linked to any other crime. I am confident that there is very low risk to the community, although I understand that this has been very upsetting and disturbing for everyone, especially those who were in the area at the time.
Police are appealing for witnesses after a man died after being shot in Hove last night.
Chief Inspector Helen West said: "This is a fast moving, developing inquiry to identify and trace the person or people responsible.
"We are actively seeking the offender, who we believe has left the area, and a number of police units including CID, Neighbourhood Policing, Road Policing and dog units are involved in this inquiry at this time.
"We are in the early stages of the investigation. We are talking with a number of witnesses and have secured the scene for forensic examination."
