A waiter was been found guilty of helping his schoolboy cousin take revenge on his ex-girlfriend by murdering her in a house fire.
Shihabouddin Choudhury, 21, of Coventry Road, Nottingham, was recruited by 14-year-old Akmol Miah to help torch the home of Maleha Masud.
Maleha and her 21-year-old sister Nabiha died as as result of the blaze which took place in June last year in Tooting, south London.
Miah, now 15, of Broadway Avenue, Croydon, was convicted of their murders on Wednesday at the Old Bailey by a unanimous verdict, as well as the attempted murders of the girls' brothers Zain and Junaid, and mother Rubina.
Choudhury has been found guilty of the same counts by an 11-1 majority.
Both face life sentences when they are sentenced on July 9.
A third defendant, 19-year-old waiter Rasal Khan, of Earl Howe Street, Leicester, was cleared of all the charges.
The court heard that the fire was started by petrol poured through the Masud family's letterbox in revenge after Miah was dumped by Maleha.
A day before he searched on Google for "how to burn someone's house down".
