Questions have been raised about voter registration forms in Lake County, Indiana that were submitted by the group ACORN.

CROWN POINT, Indiana (CNN) - More than 2,000 voter registration forms filed in northern Indiana's Lake County by a liberal activist group this week have turned out to be bogus, election officials said Thursday.

The group - the Association of Community Organizations for Reform Now, or ACORN - already faces allegations of filing fraudulent voter registrations in Nevada and faces investigations in other states.

And in Lake County, home to the long-depressed steel town of Gary, the bipartisan Elections Board has stopped processing a stack of about 5,000 applications delivered just before the October 6 registration deadline after the first 2,100 turned out to be phony.

"All the signatures looked exactly the same," Ruthann Hoagland, a Republican on the board. "Everything on the card filled out looks exactly the same."

The forms included registrations submitted in the names of the dead - and in one case, the name of a fast-food restaurant, Jimmy Johns. Sally LaSota, a Democrat on the board, called the forms fraudulent and said whoever filed them broke the law.
