Inquiry over unconscious Torquay prisoner
The Independent Police Complaints Commission (IPCC) is to investigate after a man was found unconscious in a Torquay police cell in March.
The 34-year-old was later treated at Torbay Hospital for a methadone overdose and possible pneumonia.
The man's mother complained to Devon and Cornwall police in April saying officers should have known his history.
The IPCC said the complainant had appealed to them in August and it decided to independently investigate.
The mother of the man from Torquay, has complained that custody and medical staff should have taken greater care of him to prevent him being found unconscious.
IPCC Commissioner Rebecca Marsh said: "This was a serious 'near miss' incident in police custody and we will also be considering why the matter was not referred to us either at the time of the incident itself or when the complaint was made.
"The IPCC investigation will consider the whole circumstances of the man's detention, which will include his arrest and custody prior to his arrival at Torquay police station."
Devon and Cornwall Police said it did not comment on IPCC investigations.
