The crash happened at the entrance to Altnagelvin Hospital

An ambulance was sent 16 miles to help a pregnant woman injured in a car crash which took place outside a Londonderry hospital, it has emerged.

The incident happened outside Altnagelvin hospital in October, but details have only just been released.

An ambulance service spokesman said an ambulance was sent from Limavady because Derry ambulances were on emergency calls.

"It is generally a system that works extremely well," he added.

"While Limavady were covering in Derry we were confident Coleraine would be able to cover the likes of Limavady."
