Woman shot in arm near Melbourne reserve

A woman has been shot in the arm while investigating sounds of gunfire at a reserve near her Melbourne home.

The woman, aged in her 60s, was taken to Sunshine Hospital with non-life-threatening injuries after she was shot about 4.45pm on Monday.

It is believed the woman had looked over the back fence to see where the shots had come from and when she got down she was hit in the arm by the bullet.

Investigators are unsure whether the shooting was intentional or a ricochet and are searching the area.
