A 56-year-old male is being investigated in South Korea on fear of starting a dangerous fire that killed 30 individuals.
The person, who has not been named, was performing an ancient ritual by a home tomb on a hills in Uiseong region, North Gyeongsang state, at the time.
He has been booked- but no arrested- and will be called in for questioning once the analysis of the page has been completed. He denies the claims.
On Sunday, officials said the key fires had suddenly been brought under full control- 10 days after they started, causing popular damage to buildings, including ancient temples.
Researchers reportedly spoke to the criminal’s child who is said to have told them the blaze began as her father tried to burn tree trees hanging over the graves with a cigarette lighter.
According to the Korea Forest Service, the flames burned more than 48, 000 acres- equivalent to around 80 % of the size of the money Seoul.
They even destroyed an estimated 4, 000 structures, including homes, businesses and a number of national riches.
Goun Temple- a Unesco World Heritage Site- was among the churches destroyed in the incident. It was built in 618 AD and was one of the largest in the county.
Most of the deaths were citizens in their 60s and 70s.
Even though the main fireplace has been brought under control, smaller people continue to revive, officials say.
Fuelled by robust and dried winds, the flames spread to many cities and counties.
Unusually hot weather, dry conditions and pine trees in the region even helped fuel the lights.
An investigation involving the officers, fire officials, and forest management may be carried out next week.
Acting President Han Duck-soo said the state may provide monetary aid for those who have been displaced by the flames.
