An employee in the Nassau County Clerk's office has been arrested and accused of altering election ballots.

Jonathan Maldonado allegedly placed altered sample ballots on a sign-in table to help a legislative candidate.

Officials say it happened during last September's primary.

According to officials, on those ballots, there was a hand written message that said “Fill in Oval Here” with an arrow next to the name of the candidate Maldonado campaigned for.

The 36-year-old is now charged with electioneering and faces up to a year in prison.
