A senior Tanzanian opposition politician has been arrested just days before the country heads to a crucial general election, heightening fears of a government crackdown on dissent.
John Heche, the deputy chairperson of the main opposition party Chadema, was detained in Dar es Salaam while attempting to attend the treason trial of his party leader Tundu Lissu.
Chadema officials described Heche’s arrest as part of a broader government plan to silence opposition voices ahead of the October 29 vote.
In a statement released on Wednesday, the party claimed that the authorities were plotting to detain senior party leaders until after the election to weaken the opposition’s ability to mobilize supporters.
“The government intends to arrest senior Chadema leaders and detain them until after the polls,” the statement read. “This is a deliberate attempt to crush democracy and silence alternative voices.”
The Tanzanian government has not issued an official response to the allegations, and police have declined to comment on Heche’s arrest.
According to Chadema, Heche was detained at the High Court premises in Dar es Salaam as he arrived to attend Lissu’s hearing.
The party further alleged that Heche was being transported to Tarime, a town in northern Tanzania more than 1,300 kilometers from the capital, where he could face new charges.
This marks the second time in a week that Heche has been arrested. Last Saturday, he was detained briefly while attempting to cross into Kenya to attend the burial of former Kenyan Prime Minister Raila Odinga.
Tanzania’s immigration department said Heche had tried to cross the border illegally, a claim that Chadema dismissed as politically motivated.
“This is harassment and intimidation,” the party said. “Heche was on his way to attend a public funeral, not to commit any crime.”
The latest arrest comes amid rising tension following the reported abduction of Humphrey Polepole, a former Tanzanian ambassador and outspoken critic of the government.
Polepole’s family said he was abducted at his Dar es Salaam home on October 6. His brother told The Africa Standard that he found signs of a violent struggle, including a broken door and bloodstains.
The police have yet to confirm Polepole’s whereabouts, and the incident has deepened public concern about the state of human rights and political freedoms in Tanzania.
President Samia Suluhu Hassan, who assumed office in 2021 following the death of President John Magufuli, is seeking a second term under the ruling CCM party.
Her first months in power were marked by optimism after she lifted bans on opposition rallies and promised national reconciliation.
However, in recent months, her administration has been accused of reverting to repressive tactics, including arrests of journalists, opposition figures, and activists.
Tundu Lissu, Chadema’s presidential candidate and a key opposition figure, has been detained since April on charges of treason. His supporters say the case is politically driven to bar him from running.
Chadema, Tanzania’s largest opposition party, has been disqualified from next week’s election, effectively leaving President Samia without a serious challenger.
Luhaga Mpina, the presidential candidate for ACT-Wazalendo, the country’s second-largest opposition party, was also barred from contesting after electoral authorities claimed irregularities in his nomination papers.
The disqualification of the two main opposition candidates has sparked outrage among civil society groups and international observers who say the credibility of the upcoming vote is now in question.
Political analysts warn that the growing suppression of opposition voices could push Tanzania toward political instability and undermine its democratic gains.
“This election is taking place in an atmosphere of fear and intimidation,” said a political analyst based in Dar es Salaam. “The detention of opposition figures days before voting is a clear signal of shrinking political space.”
Human rights organizations have urged the government to respect the rule of law and allow all candidates to campaign freely, warning that failure to do so could lead to post-election unrest.
Despite the tension, President Samia’s supporters maintain that the election will be fair and peaceful, citing her government’s commitment to stability and economic progress.
As the country prepares to vote, opposition leaders are calling for calm and urging their supporters not to resort to violence.
However, many Tanzanians remain fearful that the escalating crackdown may signal the return of the heavy-handed tactics seen during Magufuli’s rule, when dissent was crushed and opposition activity was tightly controlled.
