Kasambara last evening said he was detained indefinitely alongside four others after police visited his offices in Blantyre on an alleged kidnap tip off.
The other detainees have been identified as Arthur Chikankheni, Mayamiko Kadango, Brian Magoya, Patrick Gadama and Ali Kaka.
Blantyre Police spokesperson Beatrice Mikuwa said Kasambara and the other five have been charged with assault occasioning bodily harm.
She said the trio is in hospital and has not been charged with any case.
But Kasambara said: “Police came [to my offices] after lunch and left with the three self-confessed plotters. They [police] claimed to have received a tip off from an anonymous call that three men had been kidnapped and were at my office.
“I donÃ¢â‚¬â„¢t know where the three men were taken to, but we were told they had been taken to hospital. They might have been freed.”
Earlier, Kasambara claimed his office premises at Magalasi in Blantyre were raided by five people at about 10 am allegedly on a mission to kill him.
He said the alleged attackers did not know him personally and attempted to get a description of the type of car he drove from some women selling their wares near the entrance to his office premises.
Kasambara said one of the women sneaked into his office and tipped him off about the suspicious men, after which he left the premises, driving past one of the men who was talking on the phone.
He said that the apprehended trio confessed during interrogation to have been sent by some Democratic Progressive Party (DPP) officials (names withheld). He said two others escaped.
But DPP spokesperson Hetherwick Ntaba said he did not have information on the issue.
Last month, Kasambara was summoned by Southern Region Police Commissioner Rodney Jose alongside UDF director of research Humphrey Mvula for allegedly inciting disaffection for President Bingu wa Mutharika through the ongoing strike by Judiciary support staff. The strike has paralysed the countryÃ¢â‚¬â„¢s justice delivery system for six weeks now.
Over the weekend, Kasambara granted an interview to Weekend Nation, during which he argued Mutharika must resign for failing to run the country.
