Police say they have re-opened the case following a complaint made implicating Yoshitha Rajapaksa, the son of the former President, in his death.
According to Police sources, Thajudeen's death was not fully investigated after it transpired that a powerful political hand was behind the mystery.
A top source in the Police said the complaint states that both Thajudeen and Yoshitha had a serious personal rift over a girl.
