Police Scotland issued a statement regarding the event: “At approximately 5 p.m. on Thursday, March 19, 2026, we were alerted to two individuals attempting to gain access to HM Naval Base Clyde. A 34-year-old man and a 31-year-old woman have been detained, and investigations are currently underway.”
