Johannesburg - The people responsible for Neil Aggett's death continue doing business with the state, the Food and Allied Workers' Union said on Thursday.

“Some of Aggett's killers were still doing business with the state on security and related services,” Fawu national organiser Lekgotla Morake said.

“We want closure and those who assassinated him should be put behind bars.”

Fawu general secretary Katishi Masemola said the union wanted Justice Minister Jeff Radebe to ensure that those responsible for Aggett's death were brought to justice.

“We repeat our call on the minister of justice Jeff Radebe... to ensure that those responsible for Neil Aggett's death are brought to justice, especially because the suspects or actual killers never appeared in the Truth and Reconciliation Commission (TRC),” said Masemola.

Aggett was a medical doctor and trade union organiser who died while in detention in the Johannesburg Central police station, previously known as John Voster Square, in 1982.

He is believed to have committed suicide after a lengthy period of torture.

Johannesburg Central police station commander Colonel Chester Spies said the memorandum would reach the relevant people.

“I would ensure that the memorandum reached the relevant role players... and thank you for your peaceful protest outside the police station,” said Spies.
