"My team and I need to speak to anyone who witnessed the incident or the moments leading up to it.
"We particularly want to speak to anyone who was at Malvern Link Station at the time, and there were dozens of commuters on the platform, especially one man who was among those who came to the women's aid and has not yet spoken to the police."
He said they also wanted to speak to anyone who was walking or driving along Worcester Road between 6pm and 6.15pm and saw two women "acting suspiciously on the railway bridge".
Anyone with information should contact the police on the non-emergency number 101.
