Heckmondwike fire: Four arrested over arson attack
Four people have been arrested on suspicion of attempted murder over an arson attack on a house in West Yorkshire.
The family living in the house in Stonedene Court, Heckmondwike, escaped by jumping from an upstairs window on Sunday morning.
A 17-year-old boy suffered burns and injuries from jumping.
Police said two women, aged 21 and 17 and two men aged 22 and 19 had been arrested.
Emergency services were called to the house at about 04:10 BST.
The 17-year-old boy was taken to hospital with serious injuries, while a woman and two girls were treated for smoke inhalation.
Det Supt Mark Swift said the attack "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".
Officers are still appealing for witnesses to come forward.
