Mr Dadiyata was abducted in August 2019 by suspected gunmen.
Multiple reports said the inferno engulfed Gidan Gilas, also known as “Gidan Mai,” before spreading to some adjoining structures in the market.
The police, who confirmed the arrest in a statement, said an investigation has been launched into the incident and that more arrests are imminent.
Mr Abdulrazaq said a few persons had been preliminarily identified from the video as residents of Woro.
The first dastardly attack took place at Tunga-Makeri in Konkoso Ward around 3:00 a.m.
The latest development cones days after Boko Haram terrorists killed hundreds of innocent residents in the state.
Many Nigerians on X condemned the video, accusing the government of complicity in the country’s killings and kidnappings.
INEC earlier released the 2027 election timetable, detailing dates for campaigns, voter registration, party primaries and the general elections.
The suspect is expected to appear before the Atteridgeville Magistrate’s Court on Monday.
“He was unfazed by the incident and remains committed to the battle to enthrone a better Nigeria,” Mr Abubakar added.
