Fire brigade, police and ambulance are on site, reports Kapo Aargau via Twitter.
As Blick.ch writes, the building in full flames is the seat of the neon manufacturer Neon Bächli AG.
As the building is located near the railway line, the SBB Hochdorf-Lenzburg line is interrupted – SBB should expect cancellations and delays. Similarly, nearby Luzernerstrasse is temporarily closed to traffic.
The mission is still ongoing around 22:00, but the fire is under control, confirms Kapo for "20 minutes." Three people were allegedly taken to hospital with suspected smoke poisoning. It is not known if he is an employee of the company or emergency services.
