The ex-girlfriend of a pop star was under arrest last night on suspicion of killing her French nanny and burning her body in the garden of her £900,000 flat.

Sabrina Quider, 34, whose former partner was a one-time member of a well-known boy band, was held after concerned parents walking their children home from school reported a large blaze and ‘foul-smelling smoke’.

Police raced to mother-of-two Miss Quider’s Victorian end-of-terrace home in Southfields, an affluent South London suburb, after a curious boy of eight scaled the back garden gate and saw a huge bonfire with a man throwing what he thought were ‘sticks’ on the flames.

When officers arrived at 6.30pm on Wednesday, the body was so badly burned they could not establish her age or even gender. But the victim was named locally as Sophie Lionnet, 21, a nanny from Troyes, a town in north-eastern France.

The Frenchwoman, who came to London to learn English, is thought to have been living with Miss Quider at her flat for 14 months caring for her three-year-old daughter and son aged six.

Miss Quider is separated from the father of one of her children, an Irish singer who is now an internationally successful music mogul living in Los Angeles.

On social media, Miss Quider posed for glamorous pictures on nights out at various restaurants. 

One friend of the victim said: ‘She came here to learn English, but found it very difficult here. 

Sabrina liked her social life and liked going out with her friends. There always seemed to be plenty of money. 

She has had Sophie, who is from a poor French family, living in her little home for 14 months.
