A part-time security guard has been arrested for setting fire to a building supplies store because working there made him “too stressed.”

The Ken Depot Soka Sezaki Store in the city of Soka in the Japanese prefecture of Saitama burned to the ground at around 5pm on 13th June.

Part-time worker Tatsuya Matsuzawa, 32, is facing arson charges after he admitted starting the blaze because he was burned out by stress.

He explained how he had plotted to start the blaze away from the store’s CCTV cameras with a burner that was in the store.

After the shop burned to the ground, the suspect told the police: “I was too stressed at work so I set the store on fire.”

Local media said the store was still open with several clients in the building and around a dozen employees working when Matsuzawa started the blaze.

During the fire, a 42-year-old female employee was injured and taken to a nearby hospital for treatment.

According to reports, Matsuzawa had been working for the company as a part-time delivery driver and security guard for about one year.

He has been placed under arrest as the investigation continues.
