Man fights off attempted robber on CTA train pulling into Roosevelt Station

CHICAGO (CBS)-- A man fought off an attempted robber on a CTA train as it was pulling into the Roosevelt Station Thursday night. 

Police said the victim was riding the train when a man pulled out a gun in a robbery attempt. The victim fought back and tried to wrestle the weapon away. That's when the gun went off. 

The victim was not hit, but was taken to the hospital.

The attempted robber was arrested and charges are pending. 

This is now the third violent incident on the CTA this week alone.

Two people were stabbed on separate CTA lines within hours of each other late Tuesday and early Wednesday.

A 40-year-old man was stabbed multiple times during a robbery on an Orange line train. He's still in serious condition and police released these pictures of the suspected attacker.
