A Tamil from Sri Lanka faces two life sentences after he was convicted of axing to death a 25-year-old and setting fire to a teenager in Britain.
Senthamil Thillainathan, 21, was part of a gang which brutally attacked the teenager and killed him in a park,
the jury at the Old Bailey was told.
He and an accomplice also axed to death a 25-year-old in a revenge killing.
The park murder in February last year was allegedly motiveless and involved
four men, including Thillainathan.
After beating 18-year-old Supenthar Ramachandran, they
set fire to his body and left him in a pool of his own blood.
His fire-blistered body was found the next day in Roe Park, Kingsbury,
The dead man, from Wembley, north-west London, had been repeatedly picked on by the
other Sri Lankans while they were eating in a Tamil restaurant.
They made him pay the bill before bundling him into a car against his will.
Aftab Jafferjee, prosecuting, told the jury not to look for any logic or sense
in why he was killed but accept the murder was "sheer cruelty".
A year before, Thillainathan had axed Arvinthan Muthukumarasamy, 25, across
the head allegedly in revenge for damaging a car.
The dead man was repeatedly hit over the head with the axe, exposing the bone
of his skull. He was also repeatedly stabbed.
An accomplice, Sivivageethan Punniyamoorthy, 22, was convicted of the murder
at an earlier trial. The jury was unable to agree a verdict in Thillainathan's
case and he was retried at the same time as the park murder.
The case was one of the longest seen at the Old Bailey and started last November.
Thillainathan, of Chatsworth Avenue, Wembley, had denied both murders.
Three other Tamils, Pradeep Sivanesan, 18, Kannan Sivakumar, 30, both from
Wembley, and a 17-year-old who cannot be named by court order, were convicted of
the park murder of Mr Ramachandran. They had denied the murder.
They are all due to be sentenced on Monday.
