CHICAGO -- A candidate for the Illinois House says he was attacked by his opponent's supporters.

Bob Zwolinski is running for Illinois’ 4th District, against incumbent Cynthia Soto.

He says Sunday night a man and a woman were stapling posters for Soto outside his campaign office Ashland and Chicago in East Ukrainian Village.

Zwolinski says he asked them to stop and that's when the man punched him in the chest then the woman hit him in the head with a beer bottle and then shot a staple gun at him -- leaving him with a staple in his forehead.

Chicago police say Zwolinski has filed a police report and the accused attackers are claiming they are the victims in this case.

The man claims Zwolinski attacked him.

Zwolinski was treated at a hospital, as well as the man. Zwolinski was given six stitches and treated for a cracked nose.

No one has been arrested.

WGN has not heard from Soto yet.
