A MEDICAL charity is extending its service to help paramedics treat emergency patients 24 hours a day on weekends.

The London Air Ambulance service (LAA), a registered charity, today announced an extension to its rapid response car service after an increase in donations.

At the moment, the service operates helicopters during the day with cars taking over at night.

Andrew Cameron, chief executive of the charity, said: "The extension of this service is essential for the safety of all Londoners.

"Many trauma incidents occur on Saturday nights and it is only right that a dedicated trauma response unit is on hand to help these people.

"We are so grateful for all the support that the service has received in order to make this possible".
