A man has gained access to an orphanage in Poland, killing a teenage girl and injuring nine other people, according to police in the central city of Lodz.
The 19-year-old man entered the building in the village of Tomislawice near Lodz, and attacked residents with a sharp object, spokesperson Aneta Sobieraj said.
"We know that the most serious wounds were suffered by a 16-year-old girl, a ward of this orphanage, who died on the spot," she said.
Five people were hospitalised as a result of the incident, but their lives are not in danger, Ms Sobieraj added.
Four others were treated at the scene.
The attacker was arrested at his place of residence about an hour after the incident and did not put up any resistance, Ms Sobieraj said.
State-run news agency PAP said that the attacker was the girl's ex-boyfriend and he entered her room through the window.
Prosecutors are investigating all aspects of the last period of the victim's life, including her relationship to the attacker, said Jolanta Szkilnik, a spokesperson for the district prosecutor's office.
Ms Szkilnik said that the other children from the orphanage were receiving psychological care.
At the time of the attack, 13 people were in the building, including one employee.
