Deputy Interior Minister Czesław Mroczek said on Sunday that those behind false fire and life-threatening emergency reports "will not go unpunished" after rescuers forced their way into an apartment in the Baltic city of Gdańsk belonging to a member of Nawrocki's family.
The intervention took place on Saturday evening after emergency services received a report of a fire and a threat to the lives of children inside the apartment.
Mroczek said state medical rescue teams, firefighters and police were all dispatched to the scene.
Fifteen minutes later, a second report claimed that children inside the apartment had suffered cardiac arrest.
The officer in charge decided to force entry into the apartment.
"It turned out that no one was inside the apartment, and at that point the operation was ended," Mroczek told reporters after a government briefing.
Prime Minister Donald Tusk convened the briefing on Sunday morning at the Government Centre for Security in Warsaw.
It was attended by ministers and officials responsible for law enforcement and emergency services, including Interior Minister Marcin Kierwiński, Defence Minister Władysław Kosiniak-Kamysz, Digital Affairs Minister Krzysztof Gawkowski and Tomasz Siemoniak, who oversees the country’s security services.
Tusk said state services had to act quickly to identify those responsible for what he described as "provocations" involving false emergency reports.
He added that he had spoken overnight with Nawrocki about the false alarm involving the president’s family apartment.
Mroczek said officials had briefed the prime minister on steps already taken by investigators.
He added that Poland’s emergency services receive many reports involving possible threats to life and must treat them seriously.
"This year there have been close to 1,200 such reports," Mroczek said.
The latest incident has drawn political attention because it involved an address connected to the president's family.
The case comes amid broader concern over false emergency reports targeting public figures and institutions.
