The incident took place on Wednesday morning, Polish state news agency PAP reported.
Poland’s interior ministry said in a statement on Thursday: “Yesterday at 7:50 a.m. there was an explosion in a room next to the office of the police chief. One of the presents the police chief received during his working visit to Ukraine on December 11 and 12 exploded.”
The ministry added that the police chief, Jarosław Szymczyk, had met with the heads of Ukraine’s police force and state emergency services during his visit and the gift was from one of those Ukrainian officials.
It did not specify what kind of gift Szymczyk received during his trip to Ukraine.

Police chief hospitalised with 'minor injuries'
The statement also said that Szymczyk was "taken to hospital with minor injuries" after the blast, the PAP news agency reported.
A civilian employee at Poland's National Police Headquarters (KGP) also suffered minor injuries, but did not require hospital treatment, according to officials.
“The Polish side has asked the Ukrainian side to provide an explanation,” the ministry said in its statement.
Investigation under way
On Friday, the Regional Prosecutor's Office in Warsaw confirmed it had launched an investigation into the incident.
Its spokesman, Marcin Saduś, told reporters that “due to the nature, location and character of the incident, it is not possible to provide information about the probe’s findings at this point,” as quoted by PAP.
Russian involvement?
Meanwhile, Polish Deputy Foreign Minister Marcin Przydacz said on Friday that "the causes of the explosion should be established," including "possible Russian involvement" in the incident.
Przydacz told public broadcaster Polish Radio: “Sowing discord between Poland and Ukraine is definitely one of the objectives of Russian foreign policy.”
He added, as quoted by Polish Radio’s IAR news agency: “Whether or not Moscow had a hand in this, this objective remains unchangeable for it."
