Police say they're looking for man who became angry with the owner of a gaming machine at a Wichita gas station.

The dispute happened around 10:20 Wednesday morning at the Valero at 731 N. Ridge Road. Police Lt. Doug Nolte says the man came to the store wanting to claim winnings from a gaming ticket he says he purchased at the store.

The store told him the ticket was invalid and called the owner of the machine.  The owner arrived and the man became angry.  Police say he went to his car to get a hammer and threatened the machine's owner.

The suspect left and threw the hammer through the owner's car window.  Police ask you to call 911 if you know anything about the incident.
