BUCHAREST (Reuters) - On the steps of a Bucharest court on Friday, Adrian Albu pointed to his sister among the pictures of the 65 people who died in a nightclub fire five years ago, triggering mass protests across Romania at a culture of graft and lack of accountability.

The fire broke out when fireworks used during a concert by rock band Goodbye to Gravity ignited non-fireproofed insulation foam, triggering a stampede towards the single-door exit. Prosecutors have shown the club’s owners allowed it to fill beyond capacity and that Bucharest officials gave it an operating licence while safety inspectors allowed it to run despite knowing it did not have a fire safety permit. A trial resulted in preliminary prison sentences last year, but the decision is on appeal. Badly-burned patients were treated in improper conditions in Romanian hospitals, where many contracted infections that are still hampering their recovery.
