Detectives are renewing appeals for information in one of the longest running abduction cases in the country.

On February 5, 1990 at 6.45pm, Paul Glover reported that his five-year-old son, Ames Glover, had been abducted from his car.

Mr Glover had left Ames alone on the back seat of his blue Ford Sierra (reg CLP 655Y) in South Road, Southall, at the junction with Hamilton Road.

He went to Lloyds bank cash point and then to the 'Kwality' take away curry restaurant in South Road, returning 20 minutes later.

The car had been locked. Ames was dressed in a blue and yellow coat, light green baby grow, with blue and yellow hat and blue boots.

In 1990 and 1991 extensive enquiries were made by the Area Major Investigation but to no avail.

The case was reviewed in 2001/2002 to establish if there were any further lines of enquiry that could be pursued. In June 2002 the Racial and Violent Crime Task Force took over the investigation and followed up various leads.

Following an appeal in Nov 2003 information was received by the enquiry team stating that Ames Glover had been taken to Ghana in 1990.

Officers travelled to Ghana in September 2004 offering a reward of up to £10,000 for information leading to the whereabouts of Ames.

Officers launched a media appeal, which resulted in a number of calls to the incident room all of which were followed up.

Detective Sergeant Peter Birdsall, Specialist Crime Directorate, said: "Ames Glover has been missing for nineteen years. Shanika, Ames's mother, has spent all these years not knowing what happened to him.

"I am convinced someone knows where he is or what happened to him; it has been a long time and allegiances will have changed and I hope that the passage of time and the offer of a £10,000 reward may encourage them to come forward.

"I would also appeal to their consciences and think of the agony Shanika has been going through."

Shanika Ondaatjie, Ames's mother, said: "Although I have tried to move on, there will always be a part of me that cannot. I need to know what happened to Ames and I know someone has that nugget of information that would help the police, I would ask them to come forward. I don't care if it's good or bad, I just need to know.

"Sometimes I see young boys in the street and can't help but wonder if one of them is Ames. He would be twenty years old this year and I have lived in the hope that one day I will find out where he is or what became of him."

Anyone with information is asked to contact the Incident Room on 020 7230 5311 or, if you don't want to give your name, contact Crimestoppers on 0800 555 111.
