(12/8) Police say they've arrested three people in connection with an arson attack on a house in Heckmondwike at the weekend, which they're treating as attemped murder.
A 21 year old woman, and a 22 year old man, both from Wakefield, are in custody, along with a 17 year old female from Batley.
Officers were called to a property on Stonedene Court at about 4.13am in the early hours of Sunday morning to a report of a fire at a house there.
The four occupants managed to escape from the property, with a 17-year-old male suffering burn injuries and an injury to his body as a result of jumping from an upstairs window.
A woman and two girls, aged 16 and 11, also managed to escape via windows.
They were treated at the scene for smoke inhalation and taken to hospital.
Detective Superintendent Mark Swift of the Homicide and Major Enquiry Team, who is leading the investigation, 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 for those inside.
“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 on Sunday 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.
