A video recording taken from the suspect showed what prosecutors said was a test explosion he conducted, leaving a large crater in the ground.

Polish television, citing sources close to the investigation, said the suspect planned to copy methods used by Anders Behring Breivik, who killed 77 people in bomb and gun attacks in Norway last year and said he was driven by far-right views.
