Police are making a fresh appeal for witnesses after a hand grenade was thrown into a house in Liverpool, injuring a 63-year-old woman.
Police are treating the attack as attempted murder
The device was thrown through the window of the house at Canning Road, Toxteth, on Thursday night.
The woman was left with shrapnel wounds to her leg and back.
She is in a serious but stable condition at the Royal Liverpool Hospital after surgery.
Three children - aged four months to seven years - who were in the house, suffered shock after the blast.
The woman had been in the front room of the house when the hand grenade was thrown through the window.
Merseyside Police says that confirmation that the weapon used was a hand grenade, was "a significant step forward", and is urging any witnesses to come forward.
Detective Inspector Steve Dixon said: "We are investigating an attempted murder, which has left a lady with appalling injuries, and her family shocked and deeply upset.
"We are sure that someone will know who is responsible for this attack and I would ask them to come forward and give us information which could help.
"Anyone who would commit such a indiscriminate crime, which has hurt innocent victims, should not be sheltered by the wider community, or by criminal fraternities.
