POLICE are treating an arson attack at a house in Heckmondwike as attempted murder.
Four people were forced to escape through windows to save themselves at the property on Stonedene Court in the early hours of Sunday morning.
A 17-year-old boy is in a serious but stable condition after suffering burns and injuries by jumping from an upstairs window at the semi-detached house.
It is believed he may have struck a car on the driveway below as he fell.
A woman and two girls, aged 16 and 11, were treated for smoke inhalation and then taken to hospital after fleeing the blaze, which started at around 4am.
One neighbour, who did not want to be named, said: “I heard female voices shouting and screaming and you could tell there were children in there.
“I looked out of my window and saw the smoke, so I ran out of my house and down the street to help.
“There was flames coming out of every window and door in the house, it was horrendous.”
Detectives are conducting extensive enquiries while local officers will be out on patrol reassuring the community.
Detective Superintendent Mark Swift, of the Homicide and Major Enquiry Team, is leading the investigation and said: "This is clearly a very serious incident in which a male has suffered burn injuries and three females have also suffered smoke inhalation.
"It took place at a time of night when a family were at home sleeping and could quite easily have had fatal consequences.
"We are treating this incident as an attempted murder and I am appealing to members of the public for information.
"It is quite possible the suspects will have suffered some injuries as a result of lighting the fire and I would like to speak to anyone who has information about males having turned up at home this morning with burns.
"I would also like anyone who has information about males buying petrol in cans from garages to contact us.
"Also, anyone who saw suspicious behaviour in the area of the affected property or who has CCTV of such behaviour should get in touch."
Anyone who has information is asked to contact the Homicide and Major Enquiry Team (HMET) on 101 referencing Operation PAIRGLEN and crime number 13190409679.
