A man has spent the night behind bars after he allegedly indecently assaulted a child at the weekend.
Police allege the man approached the two-year-old child sitting in a pram at Sydney's Sea Life Aquarium in Darling Harbour.
Following a brief interaction with the family, police allege the 28-year-old man leant down and kissed the child on the lips just after 5pm yesterday.
The man did not know the child or the family and was quickly pushed away by one of the child's parents, news.com.au reported.
The incident was reported to police and officers arrived a short time later.
