“Please everyone take care and stay vigilant. Not entirely sure what the developing situation is but will update if I hear anything.”
One eyewitness close to the hospital told Ayrshire Live: “There are between 10 and 15 police vans sitting on the edge of the Moorfield Estate which is about half-a-mile away from the hospital.
“It looks like an officer is standing guard outside the A&E department at the hospital.
“I’ve lived round here for a while and never seen anything like this.”
Another local said of the town centre scene: “Right now, there is a huge police presence at the first archway of the viaduct.
