Kano State Consumer Protection Council, headed by Hon. Baffa Babba DanAgundi, said it has arrested four people over the sale of the juice that led to the death of four people and hospitalisation of 189 others.
The juice had reportedly caused those who took it to be urinating blood and vomiting.
Danagundi told the BBC that the suspects were arrested in Minjibir, adding that over 580 bags of expired flavours were found in their possession.
He added that the man believed to be the leader among the suspects is notorious for selling expired products.
Danagundi said the suspects were arrested following investigations, especially in the areas where the juice was being sold, including Bakin Asibiti, Rimi Market, Singer and Sabon Gari.
Meanwhile, health authorities in Kano have confirmed the death of four people as a result of taking the juice.
Dr Bashir Lawal of the Muhammadu Abullahi Wase Hospital told the BBC Hausa service that they initially suspected lassa fever because of the symptoms shown by victims but results from tests showed otherwise.
The doctor said “four people have died, while 189 patients are receiving treatment in different hospitals in a effort to tacklie the disease.”
