Police in Michigan took a suspect into custody, after he allegedly stabbed four people on a passenger train Friday. All the victims were taken to a nearby hospital for treatment after the incident, which occurred in the town of Niles, about 100 miles east of Chicago.

The suspect was identified as a 44-year-old man from Saginaw, Michigan and the Amtrak Police Department is helping Niles city police with the investigation, according to The Associated Press (AP). The train 364, on which the attack occurred, was travelling from Chicago to Port Huron, Michigan and the attack happened when the train was at the station in Niles.

"It was terrifying and you don't think something like that is going to happen to you," Caitlin Cipri, a passenger on the train said, according to the South Bend Tribune in Indiana, adding: "It's terrifying that things like this happen."

Cipri had initially thought the attacker was punching the passenger, when she heard screaming. She had later seen the butt of the knife the attacker was carrying, with which he stabbed two other people, AP reported.

Among the people stabbed were one woman and three men, according to the South Bend Tribune, which added that one of the passengers was being taken to surgery.

An alternate train later provided transport for the remaining 172 passengers, Reuters reported.
