An appeal has been launched to trace a missing 39-year-old woman from Hitchin who has last seen in Stevenage at 1pm this afternoon.

Sarah O’Sullivan is around 5ft 2in tall, of medium build with dark hair tied back in a ponytail.

Sarah was last seen wearing a dark sweatshirt with a striped black and white top underneath, black leggings and a pair of trainers.

Officers are growing increasingly concerned for Sarah’s welfare and anyone who sees her or knows of her whereabouts is asked to contact Hertfordshire Constabulary via the non-emergency number 101 straight away.
