Luton attack: CCTV shows violent home robbery
CCTV pictures have captured the moment a man posed as a delivery driver before attacking three people in a house robbery.
He called at the property in Luton with a parcel then launched a "shocking" attack when the front door was opened, Bedfordshire Police said.
A 61-year-old woman is in a critical condition in hospital while her daughter, 26, and a teenage girl were seriously hurt.
The force has identified a suspect but said it believed he had fled the country.
