A man has been arrested on suspicion of attempted murder after a woman was attacked and two children were rescued from a Black Country house fire.
The woman, 31, was found injured in the front garden of the house in Haden Walk, Rowley Regis. She suffered serious burns to her head, back and face.
The children, a 12-year-old and a 13-month-old, were rescued from the blaze shortly before 01:00 GMT on Sunday.
They were not injured.
West Midlands Police said the 42-year-old man, from Dudley, was arrested on Sunday night. He is currently in hospital being treated for burns.
Det Con Andy Barnsley said "The woman has suffered 15% burns; we believe she was attacked in the garden before the offender deliberately used accelerants to start a fire in the property.
"Thankfully neither child was injured though the baby, who was asleep at the time, had to be rescued as smoke began filling the bedrooms."
He urged anyone with information to contact the force.
