A police spokesperson mentioned the power could be rising patrols within the space throughout the weekend.
Ch Supt Mark Chapman mentioned: “While we have already carried out extensive enquiries, we do not have sufficient information at this time to update you with the descriptions of the suspects.
“I recognize that this causes elevated concern, and I can guarantee you that we are going to replace you with these descriptions as quickly as we’re in a position to take action.”
The force said it was also reviewing CCTV in the area to build a picture of the moments leading up to the incident.
Officers are still urging anyone with information to come forward, particularly anyone who saw a woman in distress in the area of Ashley Road, Epsom, between 02:00 BST and 04:00 on Saturday.
Surrey Police has also urged people not to speculate about the incident on social media.
Epsom MP Helen Maguire previously said she was “appalled” by the incident, whereas residents in the area said they were “shocked and surprised” by the alleged assault.
