The suspect has been identified as Landilani Zagwa.
According to Public Relations Officer for Chiradzulu Police Station, Yohane Tasowana, the suspect , aged 18, is accused of killing 28-year-old Aniya Cassim.
The incident happened on Thursday around 16:00 hrs at Mwangara Stage in the area of Traditional Authority Kadewere in the district.
It is alleged that the suspect approached his aunt who was with other pumpkin vendors. They wanted to sell their produce in Limbe Township.
The deceased, however, refused to be picked, saying she wanted to board another vehicle.
This did not go well with the minibus conductor as he claimed he was hired by the deceased. A fight ensued between the two, and the conductor hit Cassim with a piece of log.
She collapsed and died on the spot.
Cassim's body is at Chiradzulu District Hospital pending postmortem.
Zagwa has since been charged with murder.
He hails from Mwangala village in the area of T/A Kadewere in Chiradzulu District.
