The precise cause of the fire, which broke out at a private commercial property on Volta Street, is as yet unknown and under investigation by the Resuce Board (Päästeamet).

According to the Rescue Board 14 cars were affected by the fire. Firefighters arrived around 04:00 EEST, with the fire not fully extinguished until a couple of hours later.

Kalamaja is a popular, predominantly residential area of largely wooden houses, but with some commerical land use too.
