Police say a woman wielding pepper spray injured herself and 18 others in a Vienna subway car when she attacked a man who complained she was talking too loudly on her cell phone.

Authorities say the incident Wednesday injured 17 schoolchildren, their teacher and the cell-phone talker herself. All were taken to the hospital.

The man who complained appears not to have been affected; police say he had left the scene by the time they arrived.

Police also say the complainer and the phone talker lashed out at each other physically before the woman resorted to the pepper spray.
