Idaho, Oregon and Washington have shutdown online sales of hunting and fishing licenses amid concerns a vendor's computer system has been hacked and personal information is at risk.

Washington state on Friday announced free fishing through Tuesday because it has gone a step further than the other two states and halted all license sales.

The states each use the same vendor, Dallas, Texas,-based Active Network to handle online license sales.

It's not clear what prompted concerns of a computer breach on Thursday or if one has actually taken place.

Active Network on its website says more than 42,000 organizers use its event and activity management software nationally. The company didn't respond to inquiries from The Associated Press on Friday.
