The local prosecutor's office, responding to the radio report, has denied that anyone in Wroclaw has been detained or charged in connection with the Norwegian killings.
The office confirmed that police visited the chemicals warehouse on Sunday following a Norwegian police request.
Breivik, however, appeared to be doing business in Poland. He wrote in his internet musings that he had purchased 0.3kg of sodium nitrate for €10 from a Polish vendor. The substance is used both in Norway and Poland as a meat preservative.
Poland's internal security agency, the ABW, appears to have checked out the alleged contacts and has just issued a statement saying that Breivik's contacts in Poland were purely "commercial".

Polish police are questioning the owner of a fertiliser company in Wroclaw about his contacts, but the deputy head of the national security agency ABW, Pawel Bialek, has told a news conference:
Quote According to our experts, the materials bought in Poland were not critical for the construction of the bomb. At this stage, the information and materials we have do not indicate that the relations with the terrorist were anything other than commercial.
No detentions have been made, and no charges brought against anybody in Poland over the case, he said.
