Tanzanian opposition leader Freeman Aikaeli Mbowe has been arrested.
Mbowe was apprehended from a hotel room yesterday night in Mwanza, in the north-western region.
According to officials from Tanzania’s main opposition party, they are yet to determine where Mbowe is being detained.
They added that the other ten leaders arrested alongside him had been taken to the Central Police Station in Mwanza.
According to local media in the East Africa nation, authorities confirmed the arrests on suspicion of inciting “unauthorised assembly”.
Chadema has been holding a couple of internal meetings to gain support.
It had pledged to hold a big political rally to advocate the drafting of a new constitution.
The opposition party said: “This is a clear sign that the dictatorship under the [late President John Magufuli] continues.”
Magufuli, who passed on in March, was accused of suppressing the opposition and restricting press freedom.
