Sydney mall reopens for tributes after stabbing attack

STORY: Many wept as they walked through the halls, with advertisements on digital screens replaced by black ribbons.

Saturday's attacker, 40-year-old Joel Cauchi, suffered from mental health issues, police and his family said.

Wearing shorts and an Australian national rugby league jersey, he ran through the mall with a knife, fatally stabbing six people and injuring at least 12 before he was killed by Inspector Amy Scott.

Normal trading will resume on Friday (April 19), while a candlelight vigil at the beach on Sunday (April 21) will mourn the victims, authorities said.
