Police have released images of the viable device which was found during a security alert in Craigavon.
Police say they believe this was an attempt by dissident republicans to murder police officers.
They have condemned what they have called a ‘cowardly and despicable act of terrorism.’
Chief Inspector Barney O’Connor said this was an attempt by dissident republican terrorists to murder police officers.
“I cannot condemn strongly enough those behind this cowardly and despicable act of terrorism. They offer nothing to this community and their actions here do not reflect the wishes of the vast majority of the law abiding residents of this area.
“I would appeal to anyone who could assist our investigation and help us identify the perpetrators to please get in touch with us by calling 101, or by calling the Crimestoppers charity anonymously on 0800 555 111,” he added.
