The attacker who committed a massacre in Poland investigated Breivik, who caused bloodshed in Norway.

He opened fire from his vehicle in the square of Krakow, Poland, on Saturday, killing 6 people and wounding 15 people; Polish citizen Michal Oksinski, whose mother, father and sister's bodies were found in his home, died yesterday in the hospital where he was injured after a clash with the police.

Polish Minister of Internal Affairs and Administration Marcin Kierwinski, in his statement about the bloody attack, stated that the 24-year-old attacker acted alone and may have been influenced by "far-right ideologies".

Minister of Justice Waldemar Zurek, who made a statement today about Oksinski, who was learned to be a factory worker, used similar expressions as Kierwinski and said that there were very strong signs that Oksinski may have been under the influence of far-right elements.

Minister Zurek stated that Oksinski was browsing websites related to anti-Muslim and pro-neo-Nazi murderer Anders Behring Breivik, who killed 77 people, most of them children, in Norway in 2011.

In June 2011, Breivik killed 8 people in a bomb attack in the area where government buildings were located, and 2 hours later, he killed 69 people by randomly opening fire at the summer camp of the Social Democratic Party youth organization on Utoeya Island.

Breivik was sentenced to 21 years in prison, the highest sentence in Norway.

Minister Zurek stated that the yellow "Gadsden flag" with a snake and the words "Don't tread on me" found in Oksinski's room was used by far-right groups in the United States.

Zurek said that some symbols found at Oksinski's workplace could also point in this direction in the investigation.
