The 999 calls for help of a convicted killer, who was afraid she was about to kill again, were not effectively acted on, a court heard today.
Nicola Edgington, who had been diagnosed with schizophrenia, went on to stab two strangers - killing one of them.
Today a judge jailed Edgington for 37 years saying she must stop blaming others.
But a report out said police officers should have done more checks on her.
ITV News UK editor, Lucy Manning, has the details:
A psychiatric patient has been jailed for life with a minimum term of 37 years for killing a grandmother in a street knife attack.
A woman who killed her mother murdered a stranger in the street following a series of police blunders, a watchdog said today.
