The Independent Office for Police Conduct confirmed it received a mandatory referral by Merseyside Police in the aftermath of the incident last week.
IOPC Regional Director Catherine Bates said: “Our thoughts are with Mr Campbell’s family and loved ones, as well as all those affected by his death.
“As he was in police custody when he became unwell, we are required to carry out an investigation into the circumstances.
“This will be thorough, and carried out independently of police, to ensure we understand the circumstances leading up to this tragic outcome.
“We will keep his family and Merseyside Police updated on our progress.”
