A tweet which appeared on Mr Hamilton’s account and was later removed could have been part of a malicious hack, police believe.

According to BBC News, the mystery tweet contained a person’s name followed by a jumble of letters.

Detective Chief Inspector Michael Harvey, head of the PSNI’s Cyber Crime Centre, said: “At this time we believe there is a possibility the account was maliciously hacked. Enquiries are currently ongoing. There are no further details at this time.”
