Nevada state authorities seized records and computers Tuesday from the Las Vegas office of an organization that tries to get low-income people registered to vote, after fielding complaints of voter fraud.

Bob Walsh, spokesman for the Nevada secretary of state's office, told FOXNews.com the raid was prompted by ongoing complaints about "erroneous" registration information being submitted by the Association of Community Organizations for Reform Now, also called ACORN.

The group was submitting the information through a voter sign-up drive known as Project Vote.

"Some of them used nonexistent names, some of them used false addresses and some of them were duplicates of previously filed applications," Walsh said, describing the complaints, which largely came from the registrar in Clark County, Nev.

Secretary of State Ross Miller said the fraudulent registrations included  forms for the starting lineup of the Dallas Cowboys football team.
