POLICE said they are extremely concerned for the welfare of 49-year-old Sibylla Childs.

She went missing in the early hours of this morning from her home address near to Queens Park, Brighton.

Detective Sergeant Pete Davis said concern was growing for Sibylla.

He said: “This is completely out of character for Sibylla as she would always make contact with her family and friends.

“She has not taken her mobile phone or purse with her and it is believed she left the house on foot.

“Did you notice a woman matching this description in this area of Brighton on Friday morning?

“We have been conducting searches, assisted by the police helicopter, in areas Sibylla is known to frequent but these have proved negative so far.

“Sibylla if you are reading this please make contact with us or your family or make yourself known to medical staff.

“Please don’t worry about your dog as it is being safely looked after until you come home. We and your family are desperate to hear from you.”

She is white, 5ft 1in tall and of medium build.

She has blonde hair which is often worn in a ponytail.

She was last seen wearing a two-layered dress, leggings and cloggs.

Anyone who sees her is asked to dial 999 immediately.

Or, if you have any information which could help us locate her, you can report it online or call 101, quoting serial 178 of 13/09.
