Kansas wildlife officials are asking thousands of nonresident hunters who received duplicate deer permits from the April drawing to give them back.

The Kansas Department of Wildlife, Parks and Tourism says a printing error sent duplicate mailings to more than 3,200 hunters in early June. The department says successful applicants should have received only one mailing, with one set of permits.

Duplicate permits can neither be used nor transferred to another hunter.

Hunters who received duplicate permits and carcass tags are being asked to return them to the KDWPT licensing station in Pratt.

The department says its staff is working with the contracted printer to find out what led to the error and to make sure all successful applicants received the correct permit.
