Officers were alerted of the shooting shortly after 1pm.
“The incident had taken place just before that,” said Marie Persson of the county police to news agency TT.
The police quickly arrived on the scene, secured the premises and let emergency services in to try to save the man’s life.
He was taken by ambulance to the Skåne University hospital, where his condition was judged to be life threatening. He died later during the evening.
According to witness statements, two men had entered the café, which two others were refurbishing, when some sort of dispute ensued.
“One of the men then pulls out a gun and shoots the workman in the head,” said police officer Thomas Paulsson to Sveriges Television (SVT).
After the shooting, the two men quickly exited the shop, leaving the bleeding victim and his severely shocked 30-year-old colleague, who managed to get help alerting police.
“He came running in here saying his friend had been shot, wanting me to call the police,” one witness told local paper Sydsvenskan.
“I thought he was joking at first but he took a deep breath and I realized that he must be serious. I closed the door and called the police.”
According to Sydsvenskan, the victim was not previously known to the police.
However, one of the owners of the café is said to be a 40-year-old former member of the disbanded Lion Family gang, which operated in the area in 2009 and 2010.
Police have yet to make any arrests in connection to the shooting.
