A young man who allegedly stabbed a woman to death and critically injured two other men on the NSW far-south coast remains under police guard in hospital.
A large-scale hunt began on Friday afternoon after a couple were attacked in their home in Bega about 3.30pm.
A 71-year-old man flagged down a passing driver outside his house on East Street after he and his wife were stabbed.
The 69-year-old woman died at South East Regional Hospital and her husband was airlifted to Sydney's St George Hospital where he remains in a critical condition.
The culprit allegedly escaped in their car and police took off after him, warning local residents to stay inside during the search.
About an hour later, the 20-year-old offender struck a 55-year-old male driver in the head with a hammer while carjacking him on the Sapphire Coast Drive in Bournda, police say.
That victim was also airlifted to St George Hospital where he remains in a critical condition, while a female passenger escaped unharmed.
The 20-year-old offender crashed 500 metres down the road and ran into bushland and officers called in helicopters, negotiators and special tactical operatives to capture him.
The fugitive was arrested about 8.20pm and taken to the South East Regional Hospital.
