Former ANC Youth League leader Julius Malema has laid charges against his ex-friend, Boy Mamabolo, Limpopo police said on Tuesday.
"Julius opened a case of crimen injuria on Sunday at 7.26pm at the Polokwane police station," Brigadier Hangwani Mulaudzi said.
Mulaudzi said police were investigating the case and were not taking it lightly.
"Threats, we do not take them very lightly, because if someone threatens you it means they have intentions... but we also have to weigh that threat," he said.
On Tuesday, The Star reported that Mamabolo allegedly threatened to exhume the remains of Malema's mother — Mahlodi Malema — from her grave and throw them in front of his grandmother's house in Seshego.
This was apparently in retaliation for Malema allegedly sending his allies to sleep with Mamabolo's girlfriend.
The newspaper reported that Mamabolo sent Malema an SMS.
"This time I want to show you that I am more brutal and exhume Mahlodi from the grave and lay her in front of (your grandmother's house). You have done many bad things to me," read Mamabolo's text message, according to the report.
He claimed Malema instructed Limpopo ANC Youth League secretary Jacob Lebogo and his ally Jossie Buthane to sleep with his girlfriend.
"In fact, one of them will die this year. I have never said anything which I didn't do."
Mamabolo reportedly admitted on Monday that he had sent an insulting message to Malema, but claimed he had been provoked.
Crimen injuria charges relate to the impairing of a person's dignity.
