Arjon Basi has faced death and overcome grief to pursue his boxing dream with his next fight on Sunday's Olympia card

Arjon Basi, still only new to professional boxing, is a ticket-seller who brings loud, raucous support. But just before his fight on Sunday night he will look out to an empty seat.

He always leaves a chair unoccupied in memory of his father.

When Basi was just a teenager, his father suffered a sudden heart attack and died.
