A person of interest is being questioned in connection with two pistol-whipping attacks on the CTA Blue Line this week.
Officers took a male into custody and allegedly recovered an airsoft gun in his backpack, Chicago police said Friday. Further information was not immediately released.
The latest attack happened Wednesday morning on a Blue Line train on the Northwest Side.
About 9 a.m., a 39-year-old woman was on a northbound train in the 1900 block of North Western Avenue when a male approached her and hit her in the head and arm with a gun, police said. The woman was taken to Saints Mary and Elizabeth Medical Center in good condition.
Police said a similar attack happened on a platform of the Blue Line Clinton stop on Monday. Surveillance images of a suspect wanted in connection with both attacks were released Wednesday.
Charges are pending.
