Man critical after Vic home invasion

A man is in a critical condition after residents confronted armed intruders in their Melbourne home.

Two men in their 20s, both with upper body injuries, are under police guard in The Royal Melbourne Hospital after an attempted armed burglary at a home in Kings Park about 6.40am on Sunday.

"The home owners fought off the intruders ... our investigation is continuing," a Victoria police spokeswoman told AAP.
