Sean Rigg 10 years Later At the foundation of the Black Thrive movement lays the proverbial ashes of Sean Rigg. Sean died in police custody on the 21st of August 2008 after being arrested by police. Since that day the family has struggled to find justice for his loss of life but have continued to fight on. On the 24th of August 2018 that fight makes its way to Oval House. Please don't miss it.
