Police are seeking the public's help to identify a man who allegedly assaulted a girl on school grounds in Adelaide's south-western suburbs.
The man allegedly grabbed a female student at Glenelg Primary School at about 10am on August 9.
The student reported the man pulled her by the right wrist from the first floor of the main building, down the stairs.
She managed to free herself at the middle landing before the man ran away.
Detectives have scoured the area for security footage and spoken extensively with students, staff and parents but have yet to find witnesses to the incident.
Police released a computer-generated image of the suspect, who is being described as about 180cm tall and bald.
He was wearing a knee-length light-blue shirt, black pants and black disposable face mask and was carrying a black beanie.
The victim reported the man had purple nail polish on one of his thumbs and wore a distinctive ring on his painted thumb, which was described as being black in colour with bright dots.
He had a black twisted bracelet on one wrist and four earrings in one of his ears.
Police are asking the public to contact Crime Stoppers with information about the man or the incident.
