Police have released CCTV images of Gemma McCluskie's last days in an appeal for fresh information about the former EastEnders star's death.
McCluskie was last seen on Thursday 1 March, when she attended the opening of the Royal London Hospital in Whitechapel.
McCluskie, 29, was carrying a Louis Vuitton bag and wearing a yellow long-sleeved top, with a round neck and navy-blue leggings.
Officers are still searching for her blackberry mobile phone which had a white phone case.

"We also urge anyone with any significant information about this case to contact us as soon as possible. In particular we would like to hear from anyone who may have seen any suspicious activity around her home address in Pelter Street in Bethnal Green."
