The casualty hurt when a car crashed into a teenage boy's bedroom at the weekend had to wait more an hour-and-a-half for an ambulance, it has emerged.

An Audi crashed into the side of a family home in Strumpshaw, near Norwich, at 2am on Sunday.

There were four people in the sporty convertible, one of whom suffered a minor head injury and a paramedic arrived on scene at 2.15am.

However, an ambulance was not available until 3.41am to take the casualty to the Norfolk and Norwich University Hospital.

One of the residents in the house, Ben London, 15, escaped serious injury after the car crashed into his bedroom, causing serious damage.

A spokeswoman for the ambulance service said: 'We are investing 160 extra hours' vehicle coverage a week in Norfolk which will also be better deployed to where patients need it so we can directly tackle issues relating to occasional delays. Despite meeting the targets we are commissioned for and recent improvements in performance these particular calls were not satisfactory and we will be carrying out full investigations into each so we can resolve them directly with the complainants. We would like to reassure the public, however, that this is not reflective of the service as a whole, where a recent patient satisfaction survey showed out of a sample size of more than 100 only one patient did not give wholly positive feedback and where compliments outnumber complaints by nearly three times.'
