One of the two hopefuls in Indonesia's presidential election has been accused of being a closet Christian, the other of being a foreigner and unfit to lead the nation.
As the race for the presidency tightens, mudslinging between supporters of Jakarta Governor Joko "Jokowi" Widodo and ex-general Prabowo Subianto is increasing, forcing even the police to get involved.
Jokowi's team asked the police this month to arrest the publisher of a little-known tabloid after it falsely reported that the Muslim governor from the Javanese city of Solo was an ethnic Chinese Christian.
A national police spokesman said authorities were investigating the case against Obor Rakyat, or People's Torch, a newspaper available in Islamic boarding schools and mosques across Java.
Jokowi has been forced to defend himself against the attacks, which are mainly focused on his race and religion - potent topics in a country that is 95 percent native Indonesian and has the world's largest Muslim population.
Some opinion polls show that Jokowi's once huge lead over Prabowo has shrunk to single digits, a rapid decline that pollsters attribute to a successful smear campaign against the frontrunner ahead of the July 9 election.
"People in rural areas and people with middle to lower income and education tend to believe the black campaign (against Jokowi). That is why the electability of Jokowi is decreasing significantly," said Burhanuddin Muhtadi, the executive director of pollster Indonesian Political Indicator, which surveyed thousands of potential voters on the topic.
Jokowi's party, the Indonesian Democratic Party of Struggle, recently posted a photo on social media showing the candidate among Haj pilgrims in 2003, proof, it said, that he is Muslim.
Meanwhile, some of Jokowi's supporters have stepped up their own negative campaigning against Prabowo.
