All three cities are located in the state of North-Rhine Westphalia.Earlier this month, police arrested a 35-year-old German-Iranian man who was allegedly responsible for the attack in Bochum and who attempted to recruit another individual for the attack in Dortmund. According to the ARD broadcaster’s Kontraste program on Thursday night, local police suspect that the man is connected to Ramin Yektaparast, the founder of the Hell’s Angels chapter in the city of Mönchengladbach.
