Millions worth of property was lost after a fire razed shops and businesses in Homa Bay town market on Saturday.
The fire, whose cause is yet to be established, started at around 12.30am along Shivling street within the town.
Charles Juma, a witness, said efforts to put out the fire using twigs failed.
"It escalated spontaneously to other shops," he told journalists.
Homa Bay Giant Traders Association secretary Jack Nyambega asked police to expedite investigations over the incident.
He said it is the second time traders in the market are experiencing losses due to fire.
"The frequency of fire outbreaks in the market raises eyebrows," he said.
Early this year, more than 20 traders lost property worth Sh5 million when their stalls were razed.
Area OCPD Esau Ochorokodi said on Saturday they are contacting affected traders to record statements from them.
He said they are yet to establish the value of properties lost, but noted that there were no casualties from the incident.
