The identity of the two young women believed to have been snatched in broad daylight in Brentford is still a mystery, say police.
Witnesses saw a terrified women with masking tape across her mouth being driven away in a maroon Ford Transit van last Friday afternoon in Albany Road and heard screams coming from the back.
But despite a wide-spread appeal for information that has lead to several calls from the public, police still do not know who the possible victims are.
Officers from Hounslow CID released this CCTV image of the van which was driven by a white man with bushy grey hair.
A police spokeswoman said: "We are still appealing for information. We have had several calls in from the public but we have had no missing persons reports for the two women and we continue to investigate."
Anyone with information should call Hounslow CID on 020 8247 6160 or to remain anonymous Crimestoppers on 0800 555 111.
