Moscow, Russia (CNN) -- The chief of Moscow's firefighting service died in a blaze that broke out at a business center in the northern part of the city, Russian media reported Sunday.
Col. Yevgeny Chernyshev went missing after he entered the building to help evacuate people after the blaze broke out in the business center Saturday night, according to the state-run news agencies RIA Novosti and Itar-Tass.
His body was later found, Mikhail Verzilin, senior emergencies ministry official, told reporters. It was believed Chernyshev died when the building's roof collapsed.
By the time the first fire crews arrived at the site of the fire, it had spread to all floors, Itar-Tass reported. Chernyshev personally assisted in evacuating people, the news agency said. Those evacuated from the building were not hurt -- RIA-Novosti said there were six evacuations, while Itar-Tass said there were 30.
Some 25 firefighter units and 30 fire engines were used to fight the blaze, which at one point spread to 1,000 square meters, according to RIA-Novosti. The fire was out as of Sunday.
Yevgeny Bobylev, a local emergencies ministry spokesman, told RIA-Novosti, "We also do not understand why the fire alarm did not work and if it ever existed." He said the building was renovated in 2009 and flammable materials were used.
