Wichita ? A former police chief and three other ex-officers have now been indicted in a gun sale conspiracy at the Bel Aire Police Department.

Grand jury indictments handed up Tuesday against ex-chief John R. Daily of Bel Aire and former officer Ricky L. Swanson of Wichita are the two latest in what prosecutors say was a conspiracy to buy discounted firearms. Both were charged with wire fraud and mail fraud.

Federal prosecutors allege the officers falsely represented the weapons were police department property to take advantage of special pricing and tax exemptions.

Court records do not show whether they have an attorney, and no one returned a voice message left at Daily’s home.

Two other former officers were charged in December for their roles in the scheme.
