£10,000 reward for information after teen Carmel Fenech's disappearance 25 years ago

• Abigail Bracken's report includes interviews with Carmel's mother, Deirdre Fenech, and with DI Chris Rambour from Sussex Police.

A £10,000 reward is being offered for information as detectives continue to investigate the disappearance of a teenager 25 years ago.

Carmel Fenech, 16, also known as Carmel Pendry, was last seen in 1998.

Sunday 21 May marked the 25th anniversary of the last known sighting of her.

Carmel was living in the Broadfield area of Crawley at the time and police fear she may have been murdered.

Police say that Carmel had last been seen at Camberwell Green Magistrates' Court in South London on 21 May 1998, with a man.

She did not return home and her mother reported her missing the following month.

Ever since, police enquiries have focused on the South London area from where Carmel and her family had come.

They had lived on the North Peckham Estate before moving to Crawley less than a year before she disappeared, and Carmel had many friends in that area and nearby Brixton and Stockwell.

She had few contacts or friends in Crawley and virtually all the information received suggests that prior to her disappearance Carmel frequented the Brixton and Stockwell areas.

Independent charity Crimestoppers have offered a £10,000 reward for information leading to the arrest and conviction of anyone linked to her disappearance.

Detective Inspector Chris Rambour, of the Surrey and Sussex Major Crime Team, said: "Carmel's disappearance has had widespread media and other publicity over many years, and although no trace of her possible whereabouts has ever been found, her disappearance has not been forgotten.

"We particularly want to identify and speak to the man who Carmel was last seen with on 21 May 1998 as he may be able to provide with information that will assist us with locating her.

"There is currently no description of him, but he clearly knew her.

"Further lines of enquiry in London were identified by recent reviews and we have been working with the Metropolitan Police to examine these and pursue them where possible, although so far they have not led to any significant developments.

"We have also been keeping in touch with Carmel's mother, Deirdre, and have fully discussed the case with her. She will be kept informed of any developments.

"Together, we and Deirdre hope that this renewed appeal, combined with the enquiries we are still carrying out, will jog memories and consciences in South London.

"The answer is out there and we really want to find out what has happened and help achieve justice and closure for her family, even after all these years.

"We will always examine and wherever possible follow up any other new information that may lead to new lines of enquiry.

"We have completed a thorough enquiry into Carmel’s disappearance which has included....keeping her family informed throughout. We have assured them that we are doing all we can to help find the answers they desperately need.

"There is information that there was a man at Camberwell Magistrates’ Court when Carmel was there and we are keen to talk with him. We will be meeting with the family to discuss the concerns that they have."

Carmel's mother, Deirdre Fenech, said: "My family have been left in limbo for 25 years. Not knowing what has happened to my daughter Carmel has had a devastating effect on my physical and mental health.

"We continue to function because we are a very close family and continue to support each other.

"A huge part of my life is empty without my daughter Carmel. Please if anyone has any information concerning her whereabouts or any other information please let us know so we can finally get an answer. I thank you in advance for your help."
