In order to conduct their duties, Police Ombudsman investigators have the powers of constable when conducting their enquiries.
This means that, when required in connection with an investigation, and with lawful authority, they can search police premises and filing systems and seize documentation and other police material.
They can also establish incident scenes and direct Crime Scene Investigators and forensic services at the scene.
The power of constable also grants Police Ombudsman investigators the power to arrest police officers if absolutely required to progress an investigation. This is not a power that is regularly used.
Unless it would be prejudicial to an investigation, the arrest of police officers will usually be undertaken by appointment.
