A 38-year-old man was injured when he was stabbed with a knife in Mannheim’s city centre and then robbed of his wallet. According to police, the incident happened early Saturday morning shortly after 05:30. The victim was on his way home in the inner-city area when he met up with a friend near squares K 2 and K 3. A group of three young men approached, spoke with the pair briefly in a foreign language, and then one man allegedly grabbed the 38-year-old from behind. The victim was reportedly stabbed in the left thigh with a knife. A second man then allegedly took his wallet, including cash, from his trouser pocket. The injured man went to a hospital on his own for medical treatment. He later reported the incident to the Mannheim-Innenstadt police station during the night from Saturday to Sunday. Police said he did not immediately call the police because he was intoxicated and had initially underestimated the severity of the injury and the incident. The Criminal Investigation Department of the Heidelberg Criminal Police Directorate has taken over the investigation. Police are asking for witnesses who observed the events or can provide useful information to contact the Mannheim-Innenstadt police tip line at 0621/174-4444.
