A group of demonstrators gathered outside the home of South African Communist Party (SACP)'s Solly Mapaila on Tuesday, hurling abuse and threats.
Mapaila says a group of people arrived in a kombi with placards, chanting pro-Zuma slogans, intimidating his family.
The second deputy general-secretary says no amount of intimidation will stop him from calling President Jacob Zuma to account.
They came here so that I can stop criticising President Zuma.— Solly Mapaila, SACP deputy general-secretary
These intimidation tactics won't succeed.— Solly Mapaila, SACP deputy general-secretary
Mapaila says the SACP has opened a case with police and have applied for a restraining order.
In April, the SACP revealed footage which showed a suspected gunman attempt to assassinate Mapaila at the annual Chris Hani wreath-laying ceremony where he was also heckled by ANC supporters.
According to Mapaila, Gupta-owned TV channel ANN7 were the first reporters to arrive on the scene and were given a heads up about the protest outside his home.
On Monday, EFF leader Julius Malema warned the SACP to increase Mapaila's security detail.

Mapaila says the SACP has taken steps to increase their security measures.
