An asylum seeker who "calmly" walked into a bank and stabbed a man inside to death without provocation or motive has been jailed for life.

Haybe Cabdiraxmaan Nur stabbed Gurvinder Johal, 37, through the heart in an attack caught on CCTV at a Lloyds Bank branch in St Peter's Street, Derby, just after 14:30 BST on 6 May.

Mr Johal's family said Nur - who Derby Crown Court heard arrived on small boat in the UK after spending a few years in Europe - was a "coward and demon" who had robbed his three young children of their innocence.

On Wednesday, Nur was jailed for at least 25 years.
