Two 16-year-old boys have been charged with arson following a blaze which caused more than £50,000 damage to a bus.

The bus's top deck was gutted after fire ripped through it in Dartford Road, Dartford, on July 31.

The driver had to evacuate passengers as the blaze took hold.

The teenagers, from Bexley and Eltham, are due to appear at Dartford Magistrates Court on 12 September.
