Vic police guard wounded stabbing suspect

It's not clear when homicide detectives will get to question a suspect in the stabbing death of a man in Melbourne.

Police say the victim, a 46-year-old Seaford man, was stabbed at one address, then staggered to a second location before he was taken to hospital with life-threatening injuries.

He died in hospital on Tuesday afternoon.

A 45-year-old man is under police guard in The Alfred hospital in a critical but stable condition with two gunshot wounds sustained on Tuesday morning when heavily armed police ended a 14-hour siege.

Police say they stormed the house because the man began stabbing one of three women he had threatened to kill during the stand-off.

The woman, 37, was taken to the Frankston Hospital with a leg wound.

She, two other women, aged 44 and 32, and a man aged 65, from Frankston, who were in the house, spoke to police about what happened.
