Yuppie Richard De Vahl didn't hesitate when a mugger attacked him... he clocked him with his mobile phone. The thief collapsed stunned, then fled empty-handed.
Richard, 26, a property consultant, carries his £2,000 phone with him everywhere.
He said yesterday that the black mugger threatened to stab him if he didn't hand over his cash.
Richard, of Fulham, London, added: "I wasn't over-pleased at this, so I smashed my phone over his head.
He reported the incident to local police.
A spokesman said: "We are looking for a man complaining of bells ringing in his head..."
The arrival of the mobile phone in the 1980s was a boon to yuppies.
