The death of his uncle led Jamie Gardiner on a journey from Blackburn to central London. Alongside three relatives, he joined around 200 other bereaved friends and family for the annual United Friends and Families Campaign (UFFC) march on Saturday 29 October.
Established in 1997, the UFFC is a coalition of those affected by deaths in police, prison and psychiatric custody.
Mr Gardiner wore a white t-shirt bearing an image of his uncle John Gardiner, who died after being arrested by Lancashire Police on May 10 1996.
First Minister Nicola Sturgeon has refused to commit to a full inquiry into custody arrangements in Scotland in the wake of the death of Sheku Bayoh in Fife two years ago.
However, the SNP leader promised her government would see what lessons could be learned from a UK inquiry. Dame Elish Angiolini’s report called for a ban on former police officers leading custody death investigations. She also wanted a team of independent investigators to be on call 24 hours a day.
Mr Bayoh, 31, died after being restrained by officers responding to a call in Kirkcaldy in May 2015.
