Tuesday afternoon, several people attacked each other at Warschauer Strasse suburban train station. A knife is also said to have been used in the course of the conflict. Shortly after 5 p.m., a group of four people came into conflict with two unknown men for reasons not yet known. One witness observed a person from the group stabbing the unknown person with a knife at the entrance to the suburban railway station. All those involved then fled the scene of the crime.The four men, aged between 19 and 25, were arrested shortly thereafter in the vicinity of the railway station by alerted police forces of the Berlin State Police. A 24-year-old man put up considerable resistance and spat at the police several times. The officers found the bloodied knife in a trash can. The Federal Police assumed responsibility for the case and initiated investigation proceedings against the four Syrians for dangerous bodily harm. The 24-year-old also has to answer for resistance to police officers, assault and insult. After all police measures had been completed, the men, some of whom had already been known to the police, were able to leave the office again. As part of the further investigations, the officers are searching for the two possibly injured victims of the attack. Witnesses who can provide relevant information about the crime or the identity of the two men involved in the dispute are requested to report to the Federal Police.
