Five police officers in western Japan have been disciplined for allowing a detained suspect to use a smuggled smartphone.
The Kochi Prefectural Police Department says the suspect had concealed the smartphone in his underwear when he was arrested and detained in June.
A metal detector sounded an alarm, but the officers ignored it, judging that the suspect would not be able to hide anything in his underwear.
The suspect called his acquaintance while in detention. He also took photos and sent them to people.
The smartphone was eventually discovered by an officer who became suspicious when the man was in the toilet for a long time.
An inspector and four officers have been disciplined for the incident.
The department says it will work to prevent a recurrence by ensuring that officers make stricter checks for suspicious objects.
