A body has been found in the search for a missing teenage girl, police have confirmed.

15-year-old Seesha Dack was reported missing on Sunday from South Shields, in north-east England, sparking a wide scale operation.

Police said on Tuesday a body, which they believe to be Seesha, was found near Tanners' Bank, Chronicle Live reports.

Superintendent Barrie Joisce, of Northumbria Police, said: “This is an extremely sad conclusion to an extensive investigation."

Seesha vanished on Sunday in a disappearance which was said to be “out of character” for the teenager.

She had never gone missing before before she was last seen.

A police boat and helicopter were seen around the Fish Quay in South Shields on Tuesday morning and officers were also conducting land searches in derelict buildings and outhouses before the sad discovery was made.

Tanners' Bank was cordoned off under the railway bridge at the A193 junction from around 6.30pm on Tuesday evening as a number of police officers arrived on the scene.

Police said a formal identification as yet been carried out but they believe the body is Seesha.

Superintendent Joisce said: “Specialist officers are currently supporting Seesha’s family during this incredibly difficult time and our thoughts are with them.

“I want to thank everyone who helped in our search by sharing our appeals, searching the area and those who have phoned us with possible sightings.

“We will continue to carry out enquiries to establish the circumstances around the death but at this stage we do not believe there to be any third party involvement.”

Once formal identification has been completed a report will be prepared for the coroner.

The death is not being treated as suspicious.

Police had said previously: "It is out of character for Seesha to go missing and I think that is probably the most alarming thing of this specific female going missing.

"She's 15-years-old, loving, comes from a lovely family. She's never done anything like this before and that always screams out alarm bells. There's no explanation and we don't like unanswered questions.

"Her family are extremely worried, really really worried. They are being brave and they are being fully co-operative with the police working with us and want to help as much as they can."
