Omaha police are warning area residents of a text scam promising a $1,000 gift card from retail store Target.  Police say Target has nothing to do with the text, which seeks to have the recipient enter personal information on a website.  The text says recipients can or have won $1,000 from Target, and that the receiver signed up for contest.  Omaha police say Target officials are working to have the Target name removed from the bogus website.
