SA man shot through bedroom door

An Adelaide man who was shot at through his bedroom door in a targeted attack by intruders is lucky to be alive, police say.

A six-year-old child sleeping in another bedroom may have seen some of the assault, believed to be drug-related, police said on Sunday.

The incident unfolded when at least two men forced entry to the back door of the Evanston Gardens home just before 4am, where a man, woman and six-year-old child slept.

The man, 52, and woman, 43, quickly barricaded themselves in the bedroom but the offenders fired several shots through the door, two of which hit the man, police said.

They then fled.

The injured man was taken to the Royal Adelaide Hospital with non-life threatening injuries and had surgery to remove two bullets from his stomach.

He remains in a stable condition.

The woman and the child were uninjured.

Chief Inspector Alex Zimmermann said the victim was lucky to be alive, adding it could have turned into a triple homicide.

"It doesn't take a Rhodes scholar to understand the dangers of becoming involved with drugs," he told reporters.

"Here's a case in point that we could be holding this conference discussing three homicides and that man is very, very lucky to be alive."

He urged people with information to contact police.
