39-year-old Thimo Sonius has a consultancy company a few meters from the building that closed last weekend. He had never seen anything suspicious there. “No, never, I didn’t notice anything,” he says. And didn’t smell anything either. Until last Saturday. “It may sound strange, but I smelled a combination of tomatoes and exhaust fumes. Then I thought: this is a strange smell. I opened my window, but the smell did not go away. Later, someone called the fire brigade. .”
