A Pakistani national was arrested today on suspicion of attempted murder after an 11-month-old boy and his mother were stabbed in west London.
Rehan Khan, 25, handed himself in to police after the attack at a home on Swinfield Close, Hounslow, on Monday evening.
The baby is in a critical but stable condition, while a 32-year-old woman has been treated for less serious knife wounds, police said.
Khan is known to the victims, the Met said. Some reports said he was the ex-partner of the injured woman.
Blood was splattered on the wall and floor at the entrance to a flat in Swinfield Close in Hanworth, west London.
Police and paramedics were called to the scene on Monday evening following a report concerning residents' safety. At the scene they found the woman and infant suffering knife wounds and the pair were rushed hospital in west London by the Air Ambulance Service.
Khan is being held on suspicion of two attempted murders, the BBC reported.
A crime scene was still in place at the scene, it said.
Myrtle Cantwell, who has lived on the estate for 38 years, said: "The air ambulance was hovering and there was lots of police.
"The police came by and banged on the door where it happened. The lady next door came out and ushered them in."
Another neighbour, Leanne Gidlow, described the family as "quiet".
She added: "How could anyone do this? When this sort of stuff happens on your doorstep - I just turned cold.
"Then you hear there is a baby involved and it seems to make it all worse somehow," she added.
