LAWRENCE, Kan. (AP) -- Douglas County prosecutors are investigating pending or past cases involving two suspended Lawrence police officers suspected of dismissing speeding tickets in exchange for Kansas basketball tickets.

Also Tuesday, city officials confirmed they are investigating whether other police officers were involved in dismissing the tickets.

City officials say the person whose traffic tickets were fixed is serving a federal prison sentence related to a broader Kansas ticket scandal.

The two officers were suspended earlier this month after an FBI investigation. Douglas County prosecutors say they are trying to determine if the officers' conduct damaged their credibility in other cases.

The Lawrence Journal-World reports (http://bit.ly/w3QYJH) city officials won't name the two officers, and also refused to say how many other officers might have been involved and how many tickets were fixed.
