All trains to and from the station were halted. Police said later Friday that they had arrested three people, and railway operator Deutsche Bahn said that services were resuming. No one was hurt at the bank, police said, and they also had no information that anyone was injured outside.
The incident comes four days after an 8-year-old boy was killed when a man pushed him and his mother in front of a train that was pulling into the station. An Eritrean man who lived in Switzerland is in custody in that case.
