Four girls were indecently assaulted at the Sydney Olympic Park Aquatic Centre earlier this week.
The girls, who were aged 12 and 13 years, were swimming in the whirlpool area when they were approached by a man in the pool who allegedly indecently assaulted them.
Police officers from Flemington LAC could not locate the offender, who is described as being 20-30 years old, medium build, tanned skin, short black hair and unshaven. At the time of the assault, he was wearing dark coloured short.
