A man was also hurt after the blaze broke out at the party attraction in Koszalin.
Five girls have been killed in a fire at an escape room attraction in Poland.
The teenagers were believed to have been celebrating a birthday at the venue in the city of Koszalin, where users are locked in a room and must answer puzzles and complete tasks to get out.
The girls, aged around 15, were locked in the room and were all killed in the fire.
Police spokesperson Monika Kosiec said their bodies were found after firefighters put out a blaze in a room near the fire, but that they were not directly hit by it.
The state news agency said it is believed the girls died of carbon monoxide poisoning.
A 25-year-old man was taken to hospital with burns and could not be immediately questioned by police.
Following the incident police and fire service vehicles were pictured on a residential road near a house with an “escape room” sign outside.
