The victim was smart enough to be carrying a knife too.

From ABC Chicago: 

Six people are in custody after a stabbing attack on board a CTA Red Line train on the North Side Friday morning, Chicago police said. 

Chicago police said at about 2:03 a.m., a 42-year-old man got off a train at the North/Clybourn station and switched to another train car. A group of six suspects followed him onto the train, demanded his belongings and attacked him with a knife and broken glass bottle, police said. 

The victim also took out a knife, police said. The victim had several stab wounds and was transported to Northwestern Memorial Hospital in serious condition, police said.

Three of the alleged perpetrators have been hospitalized, all six are in police custody.

This is all part of the "Summer of Joy" Mayor Lori Lightfoot promised.
