A second member of a family-of-five who were badly injured when arsonists torched their home has died.

Nabiha Masud, 21, died on Saturday, the day after her sister, Maleha, 15, was buried.

Maleha died on June 25, four days after the attack on her Lessingham Avenue home.

Their brother Junaid, 16, is still in a critical but stable condition in hospital.

All three were rescued by firefighters when the blaze ripped through the house, Nabiha was resuscitated by paramedics in the front garden.

Zain Masud, 22 - who was discharged from hospital last week - and his mother Rubina, 53, managed to escape the fire by jumping from a first floor window.

All four siblings suffered burns and smoke inhalation following the fire.

After Nabiha’s death Tooting MP Sadiq Khan said: “Our thoughts and prayers are with the family. This is an awful tragedy and one can’t imagine what Mrs Masud is going through after losing her husband [two years ago] and two beautiful daughters.”

On Friday police launched a fresh appeal for information hours before hundreds of mourners attended the funeral.

Detective Chief Inspector Damian Allain, of the Metropolitan Police, said. “Did anyone see anything in Lessingham Avenue between 2am and 5am on June 21, or did you see or hear anything that might be useful?”

He said people would have been in the area because of the London to Brighton bike ride, which took place that day, and people in the community held information police needed.

“If people are fearful of coming forward there are special measures that we can employ to conceal your identity,” he said. “People need to examine their loyalties, if they do know something they must come forward.”

A 14-year-old has been charged with murder and four counts of attempted murder. He will appear at the Old Bailey in September.
