Two petrol bombs were thrown outside police stations in Hong Kong on Friday, ahead of a mass demonstration of public anger over plans toallow the rendition of suspects to mainland China. Police arrested four men after two petrol bomb attacks, the first of which was outside police headquarters in Wanchai at 3.00 a.m., and thesecond outside the Happy Valley police station at around 4.00 p.m. Hong Kong's South China Morning Post later reported that the arrested suspects had ties to criminal organizations known as triads. However, the motivation behind the attacks was unclear.
