Police used "unsuitable" force on Sean Riggpublished at 14:14 Greenwich Mean Time 1 March 2016
Scotland Yard said a sergeant and a police constable are suspended, while another three constables are on restricted duties.
In 2012 an inquest jury found that police used "unsuitable" force after arresting Mr Rigg for attacking passers-by and officers.
He was taken to Brixton police station, where it was decided to keep him in a police van for 11 minutes until the custody area had been cleared.
Mr Rigg was found to be unwell when he was taken into the building and later died from a heart attack.
