Several Devon and Cornwall Police have been disciplined after watchdog investigations into the death of a man a day after he was in custody.
Twenty-two-year-old Logan Peters was arrested during an altercation on a night out, and held by police in Plymouth's Charles Cross station on 7 May 2014 and subjected to a strip search.
The boatbuilder from Millbrook in Cornwall was found dead at his home the next day. An inquest two years ago ruled a series of police failures caused him to kill himself.
The Independent Office for Police Conduct (IOPC) said a police disciplinary meeting in 2015 found misconduct for a custody sergeant for failing to complete a pre-release risk assessment, and management advice was given.
Six other police officers also received management action.
Now, publishing the results of a second investigation in November 2017, the IOPC said a police officer was given management advice after misconduct was proven for failing to follow proper procedures during the detention and search of Mr Peters.
Two custody officers also had cases to answer for misconduct for conducting a strip search without proper authorisation.
Misconduct was proven for one in April. However, no further action was taken due to a "recognised lack of training in how to conduct strip searches".
The other officer had retired from Devon and Cornwall Police, so "no further proceedings can be held".
More formal training on how to carry out searches appropriately was being given to custody staff, the IoPC said; adding that the "incredibly sad case" revealed "a number of interactions ... could have been handled differently".
