Two teenagers were given life sentences in the UK today for the murder of schoolboy Lyle Tulloch who was stabbed 13 times during an argument over a mobile phone at a birthday party.

Damien Solowabe, 18, and Tobi Peters, 17, both of London, will serve a minimum 12 years after being found guilty at the Old Bailey last December.

Lyle, 15, from Peckham, had been at a party in Southwark, south-east London, last May when his friend asked to use Solowabe's phone.

When Solowabe could not find it an argument began and Lyle was chased outside and into a stairwell where he was stabbed in the chest and thigh.

"This is another tragic example of what can happen when knives are used to settle arguments," said Scotland Yard's Detective Inspector David Willis, in a statement after sentencing.
