A van used in the alleged sexual assault of a boy in Adelaide's eastern suburbs may have also tried to chase down a woman nearby, police say.
They have released an image of what the van looks like in the hope of finding the men responsible for the alleged sexual assault of a 15-year-old boy at Beulah Park at about 2am on Sunday.
Police say the boy was walking along Beulah Rd when three men jumped out of a van, with two of them holding the boy down while a third man sexually assaulted him.
With information received from the public, police say they have identified two more incidents involving a white van in the area at around the same time.
They say 30 minutes after the reported sexual assault, a woman walking along Marlborough St at College Park saw a white van driving at speed along a footpath.
She told police the van was driving between the trees and the front fences of properties.
“The van turned around and started to travel towards the woman, and she ran and hid behind a vehicle nearby,” Detective Superintendent Damian Powell said.
“She was frightened by the behaviour of the van – she thought that the van was following her.”
She called a friend and ran towards Payneham Rd before a man offered his assistance and the van drive away.
Police say the man who offered her assistance is not connected to the van in any way, but they would like to speak to him in case he has any more information that could help identify the van or its occupants.
Police also say that an hour before the alleged attack on the boy, a white van was seen driving erratically on Glynburn Rd at Erindale.
It was driving on the wrong side of the road, with its hazard lights on and doing u-turns.
Detectives have been working around the clock on the investigation and will now examine traffic cameras on the roads where the van was sighted to try and identify a number plate.
The suspects are described only as male, tall, Caucasian, aged in their early 20s, with thin builds.
Police are asking for anyone who may have information that may assist identify the van, its location or those involved in these incidents to contact Crime Stoppers on 1800 333 000.
