The Secretary of State issued a warning Thursday asking residents to check their voter registration information to make sure it is accurate.

The state says a group called Indiana Voter Registration Project turned in forged voter registration applications.

The group allegedly altered information for voters who are already registered. The group changed voter addresses without the voter's knowledge or permission, according to the state.

You can check your voter registration information on Indianavoters.com or through the Indiana Voters app.

If you find information that has been changed without your permission or knowledge, immediately contact the Secretary of State’s office at 1-866-IN-1-Vote (1-866-461-8683).  

“Election integrity and security is a top priority,” said Connie Lawson, Secretary of State. “We are working with the state police to ensure this matter is addressed quickly. I encourage all Hoosiers to be vigilant at this time and to monitor their voter registrations until the close of the voter registration deadline.”

The voter registration deadline in Indiana is October 11. The Secretary of State’s office says it believes the group will continue to operate until October 11th.

The Indiana State Police announced Thursday they have confirmed some fraudulent voter registration forms have been submitted in Marion and Hendricks counties. Police said the forms had incomplete and incorrect information at the time they were submitted by representatives of the Indiana Voter Registration Project.

Police said the investigation started in August and it has not yet been completed.

If you haven't registered to vote, you can do so on Indianavoters.com, on the Indiana Voters app, at your county clerk's office, the Bureau of Motor Vehicles or Family and Social Services.

The group issued a statement regarding the allegations:

We sincerely hope that no one in a partisan elected position is using their office in an effort to make it harder for the people of Indiana to vote.  The Indiana Voter Registration Project is a nonpartisan effort to ensure that all Indianans who are eligible to vote can do so.  As part of its quality-assurance program, the Indiana Voter Registration Project has reviewed tens of thousands of applications and identified a small handful that may have had incomplete or inaccurate information and, in those instances, we immediately informed the Registrar and asked them to double check those forms for accuracy.  We have and will continue to work with Indiana authorities to resolve these issues, so that no one is prevented from voting in November who is eligible to do so.
