One of Auckland's top police officers is being investigated by fellow police.
Inspector Richard Wilkie, the Manurewa area commander, is under investigation after an alleged assault.
Counties Manukau district commander John Tims confirmed a criminal and employment investigation is underway relating to an incident on April 2.
"The incident involved an off-duty police officer from Counties Manukau District. The incident is being independently investigated by a senior police officer from outside Counties Manukau district," he said.
"The police officer concerned has been put on alternative duties until the investigation has concluded," he said.
