A paramedic was killed instantly yesterday after he fell out of an ambulance that was bringing a patient to hospital.
He was named locally last night as Simon Sexton (43), a father of six from Stradone, Co Cavan.
The accident happened shortly before 4pm on the main Dublin Road out of Cavan town.
The ambulance was transferring a patient from Cavan to Dublin at the time.
It is understood Mr Sexton noticed that a side-door was slightly ajar. When he went to check it, he fell out of the moving ambulance on to the road.
He suffered serious head injuries and died instantly.
The scene of the accident, four miles on the Dublin side of Cavan town on the N3 at Beaghy, Stradone, was sealed off last night as garda crash investigators examined the area.
The tragedy was witnessed by another paramedic who was in the ambulance when the accident occurred.
Mr Sexton died at the scene despite desperate attempts to revive him.
His body was removed to Cavan General Hospital.
The patient in the ambulance was transferred to another ambulance and taken to Dublin.
A spokesperson for the Health Service Executive (HSE) last night confirmed the ambulance was travelling along the road when the accident occurred.
Mr Sexton was a member of the regional ambulance service.
"A paramedic lost his life this evening in a tragic accident. The HSE offers its deepest sympathies to the man's family and to his colleagues," she added.
Gardai have appealed for witnesses to contact them at Cavan garda station on 049 4368800 or the garda confidential telephone line on 1800 666111.
