The baby born through after both his parents were killed in a car crash has also died in hospital.

The child, who had been named Nachman after its father, was born through caesarean section in hospital after his parents were involved in a car crash on the way to hospital.

Nachman and Raizy Glauber, both 21, had been heading to hospital after Raizy started feeling unwell on the weekend.

However, the taxi they had hired was crashed into by a speeding BMW. Raizy was thrown from the vehicle, while Nachman was pinned into the front seat and had to be cut out of the car.

Both were pronounced dead at hospital but the child survived, but remained in a critical condition, weighing just four pounds.

However, a community spokesman has now said the baby has died.

The Glauber's were members of the Orthodox Jewish community in Williamsburg, New York.

Hours after their death, a funeral was held for the young couple in accordance with Jewish law.

Over 1,000 people lined the streets outside the Congregation Yetev Lev D'Satmar synagogue.

Nachman's cousin Sarah Gluck told the New York Post: "They (Raizy and Nachman) were always glowing. They were just starting out with their life, building a family. They were very excited. That's what makes it so tragic."

A source also told the Post that the baby will be circumcised but a funeral will not be held.

They said the baby will be buried alongside his parents at Kiryas Joel in upstate New York

Police are currently looking for the driver of the BMW and a passenger who fled the scene after the crash.

A woman who had co-signed the BMW's lease was charged with insurance fraud last night.

Takia Walker was driving the car when it crashed, but she is thought to have acquired the car under false pretence and lent it to a third party, who was not insured to drive it.
