Police custody suites across Sussex have been found to be good although concerns were raised by inspectors about mentally-ill detainees.
Prisons inspectors visited cells in Brighton, Worthing, Crawley, Hastings, Eastbourne and Chichester in February.
Inspectors said all six suites were good and had well-trained staff.
But they found some cells had points which could be used by detainees to hang themselves.
The report's main recommendations were the force tackle safety issues and only use police custody for mentally-ill detainees in extreme cases.
Assistant Ch Con Nick Wilkinson, from Sussex Police, said the force was working to address the recommendations.
