According to Paweł Kusiak, a spokesman for the Starachowice city police, a message was received from the hostel on Monday morning about a Ukrainian woman with no signs of life.
An ambulance crew came to the rescue, but medics were unable to save the Ukrainian woman.
"The ambulance crew went to the scene, despite the assistance provided, the woman's life could not be saved. Police officers worked on the spot for several hours under the supervision of the prosecutor's office," the spokesman for the Starachowice city police said.
Polish law enforcement suggests that "someone may be involved in the death of the woman".
The woman's body has now been sent for autopsy.
