It has been almost four decades since the May 13 racial riots broke out.
What had prompted the worst riots in Malaysia's 50-year history that cost the lives of 196 persons (according to official records) however remained shrouded under a veil of secrecy, although there are several versions on the matter so far.
The 'official version' of it has always been the violence was triggered off by the Chinese-dominated opposition supporters' provocation in celebrating their electoral victory which saw the ruling Alliance Party suffered a major setback.
The lack of accessible information in the public domain has been a stumbling block for those who intend to uncover the episode but a set of newly-declassified documents in London gave sociologist Dr Kua Kia Soong a thorough glimpse of the event.
On the 38th anniversary of this event, malaysiakini examines what really happened on that fateful day which left a deep scar in our psyche.
