The Metropolitan Police, sharing the images on Saturday, stressed the women are not being sought as suspects but could be “key witnesses”.

The force said officers were called to Southall Park in Green Drive at around 6am on July 17 after an unresponsive woman was found.

The Met said: “Detectives have been conducting inquiries and have identified two women who were seen in the area at the time who they think could have vital information.

“They are keen to stress that the women are not sought as suspects, but could be key witnesses.”

The images of the women, who officers would like to identify and speak to, were captured in South Road, Southall at around 11pm on July 16.

An image of a man, who officers believe could also be a key witness, was previously released by police.
