A man has been arrested on suspicion of attempted murder after a staff member of a Brighton hospital was stabbed. The victim, who is in his 50s, sustained injuries that were understood not to be life-threatening during the incident at the Royal Sussex county hospital on Sunday morning. Local police ruled out any terrorist motive for the attack. The hospital went into lockdown following the stabbing as police searched for the attacker in an area around the hospital. In a statement, Sussex police said: “A man has been arrested and police and security staff worked to ensure the safety of everyone at the Royal Sussex county hospital following a stabbing incident. “At 8.42am on Sunday (19 July) police were called to the Royal Sussex county hospital in Brighton after a report that a member of staff had sustained a stab wound. “The hospital site was quickly secured while officers have been working with security staff to confirm that nobody else had been injured and that staff and patients are safe.” The statement continued: “Following immediate police searches and inquiries a 30-year-old man was arrested in nearby Wilson Avenue at 9.40am on suspicion of attempted murder and is currently in custody for interview and further inquiries. “This apparently isolated and unexplained incident is not being treated as terrorism at this time and there is currently nothing to suggest that any other person has been involved or that anyone else is at risk.” Sussex police added that the victim’s family had been informed about the incident and confirmed the man’s injuries were not life-threatening. The Labour MP for Hove, Peter Kyle, tweeted: “Shocking news from our hospital. We don’t know yet why a member of staff was stabbed but I’m thankful to @BtonHovepolice for a swift arrest for attempted murder. All affected by this are in my thoughts, especially the victim who I wish a swift recovery.”
