In the essence of Petrov's hut, the dog found chemicals, experts will confirm this

"The examination conducted by police specialists should confirm or rule out the presence of chemical substances in the sent samples. In the coming days and weeks, police will investigate how and why the fire occurred," stated Ertner. Investigators from the fire department and the police were able to access the site of the Monday fire only today; an earlier investigation was hindered by the high temperature at the fire scene.
    From the entire complex, only part of the outer walls and the transformer station were saved. Firefighters were already called to a small fire at Petrova bouda in the second half of July. Karel Janda, the managing director of Snowy Chalet, which owns the two-hundred-year-old, heritage-protected building, told ČTK on Monday that the company must come up with a new plan for the restoration of Petrova bouda.
    Petrova bouda, located at an altitude of 1,288 meters above sea level, has been closed to tourists since 2008. The building has been damaged in recent years by humidity and vandalism. According to some experts, the construction was at risk of collapse due to its poor technical condition.
