Detectives in the UK have been given more time to question a man about the stabbing of a pregnant woman.
The woman (40) suffered multiple wounds in Sutton Coldfield, Birmingham yesterday afternoon.
Her child was later safely delivered in hospital and the baby girl is said to be doing well although her mother remains in a critical but stable condition.
A 41-year-old man is being questioned on suspicion of attempted murder.
Meanwhile, a 17-year-old boy who helped the woman has said he had to "step in".
Christian Blundell said he and his friends helped an elderly man already trying to deal with the situation, until police arrived.
They then ran to a nearby McDonald's to get napkins, drinks and coats in an effort to keep the woman warm, hydrated and to clean the blood from her.
Speaking to Sky News, he said he would do the same again if needed, adding: "It's fight or flight really - you either help them or you run away.
"I couldn't not help that woman. She was in real bad pain, she was heavily pregnant, she was in pain. We couldn't just stand there - we had to do something about it," he added.
