He was strip-searched and then placed in a cell by himself.
At 6.53pm, Ginn was found on the cell floor, appearing to have suffered a seizure.
He received medical aid but could not be saved and was declared dead at 8.05pm.
A coronial inquest found his death was a result of cocaine toxicity.
Coroner Michael Jenkin was unable to make any further findings of when and how the drug was ingested.

He also ruled that Ginn's standard of supervision at the Watch House was poor after the cell control officer failed to notice the medical event for 15 minutes, but stopped short of saying it contributed to his death.
The coroner handed down seven recommendations, including a review into staffing levels, whether detainees should have to pass through a body scanner, the role of a cell control officer, and a review of overall CCTV and monitoring equipment.
