Firefighters carried out a dramatic rescue of a man who collapsed on scaffolding at the top of a five-storey building in Ipswich today.

There were fears the patient aged in his 50s had suffered a stroke, but following an assessment he was found to have blood sugar problems.

Emergency services were called to the scene at the under-construction Birketts headquarters in Princes Street at around 1.15pm.

Four fire engines, a rapid response vehicle, an ambulance officer, an ambulance crew, a response car from the Hazardous Area Response Team and a police car were among the resources in attendance.

An air ambulance from Essex and Herts Air Ambulance was also dispatched and could be seen flying overhead, but it was later stood down.
