In the midst of the pre-Christmas rush, security guard Mohammad Hassan Al Bayati​ led a three-year-old girl from a Sydney shopping centre playground into a locked stairwell.

There were no cameras inside the stairwell at DFO Homebush, where Mr Al Bayati and the girl remained for 11 minutes on Sunday, December 18, last year.

But the girl allegedly made a disclosure to her father later that day.

In an interview with police, Mr Al Bayati allegedly admitted taking the girl down the secluded corridor, but he denied allegations that he had performed an indecent act or exposed himself to her.
