An investigation has started into a potential security breach at the PSNI.
It's after a Tweet which was posted on Chief Constable George Hamilton's account earlier.
The post is understood to have included a person's name followed by a jumble of what looked liked random letters.
It was spotted and deleted within minutes.
Head of PSNI's Cyber Crime Centre, Detective Chief Inspector Michael Harvey, said: "At this time we believe there is a possibility the account was maliciously hacked.
Adding, "Inquiries are currently ongoing. There are no further details at this time."
