Police are looking to identify two men who were spotted talking to a woman believed to be missing on the day she disappeared.
Officers said a witness has come forward and stated they think they saw Georgina Gharsallah on the evening on March 7.
She was allegedly spotted with two men in Tarring Road at the junction with Clifton Road between 7pm and 8pm.
Chief Inspector Miles Oakwell said:
“We have reason to believe the woman who was with the two men was Georgina.
“We believe a group of young people stood outside the Tesco Express may have seen the three people walk past the shop.
“If you are one of the men described, or were part of the group outside the shop, please get in contact with us immediately.”
Police have described one man as white, around 5’9″ tall, and with short dark hair.
The second man has been described as white, around 5’7″ tall, and with short brown hair with a side parting.
The last confirmed sighting of Georgina is on the morning of March 7 in Clifton Road.
She is white, 5’2″ tall, with shoulder-length dark hair, and has a Monroe-style piercing above her lip.
Anyone who sees her is asked to call 999 immediately.
Anyone with information is asked to report it online here, or call 101, quoting reference number 603 of 17/03.
