German police said the man who was found dead in a shisha bar in Hamburg early on Sunday morning was killed by gunfire. The perpetrator has not yet been apprehended, according to police. Emergency forces were called to the establishment in the northern German port city's Hohenfelde district shortly after 4:30 am (0230 GMT), but medics were unable to resuscitate the 33-year-old man. After evidence indicated the man had been fatally shot, police said the homicide division and public prosecutor's office took over the investigation. Sniffer dogs were deployed at the scene, and inquiries, particularly into the motive, are ongoing. The area around the crime scene, located on a six-lane thoroughfare, has been cordoned off, with investigators combing the neighbourhood and searching for witnesses. It comes after two men were attacked at the same bar by masked assailants in December. Some three years ago, a 27-year-old man was killed in the establishment after shots were fired at his face and heart, in what police believe was an altercation related to the drug scene.
