Malawi’s former president Joyce Banda has denied any wrongdoing in a corruption scandal that erupted when she was in office.
The police announced on Monday that they had unearthed credible evidence which raises reasonable suspicion that she committed offences relating to abuse of office and money laundering.
It is in connection with the revelations of the massive plunder of public funds known as the Cashgate scandal.
Billions of kwacha was siphoned during the plunder.
The former President, however, insists that she never did anything wrong and that she is innocent.
"I will be coming back because I never did anything wrong and I am innocent," Banda told Reuters news agency in a telephone interview from South Africa, where she had arrived from the US.
"I am the only president who got to the bottom of corruption and instituted the first-ever commission of inquiry into corruption," she added.
She was expected to proceed to Malawi after carrying out some charity work in South Africa.
More than 70 entrepreneurs, officials and civil servants have been charged in connection with the scandal which occurred between 2009 and 2013.
While president, Banda ordered an independent audit of the corruption revelations, which was conducted by British firm Baker Tilly. The findings were released in 2014.
"Baker Tilly never linked me to any corruption and the rest is what everyone knows, that even some of my cabinet members were arrested. I never shielded anyone who was found to have been part of this," she said.
Banda, who was Malawi's president for two years from 2012, left the country when she lost in an election to current president, Peter Mutharika during the 2014 tripartite elections.
Her return to prove her innocens will be the first after a three year self imposed exile.
Banda has been living in the United States, serving as a distinguished fellow at Woodrow Wilson Center and the Center for Global Development in Washington DC.
The corruption scandal led to international donors halting aid to the southern Africa nation.
