Paris, 33, told ET exclusively, "We recently filed a police report because the threats were getting out of control, getting more frequent and more intensive each time."
The stalker made anti-Semitic comments against the Hiltons, mistakenly believing that they were Jewish. In one threat, he wrote, "I know ur Jew family gives nothing."
A rep confirmed to ET that the online threats made against Paris and Rick that were initially reported by TMZ were true.
Paris explained that her actions against the online stalker were done to protect the rest of her family members from further threats. "It's a frightening and scary experience for anyone and so we decided to take steps to protect our family," she said. "Hopefully now the authorities are aware they can help put an end to this."
The Los Angeles Police Department is investigating the threats. As of now, no arrests have been made.
