Kent Fire and Rescue Service say they have been called to Gravesend 17 times over the past fortnight. Most of the fires they attend involve rubbish bins which have been deliberately set alight.
Police, Gravesham Borough Council and the Fire Service are working together to catch those responsible for the attacks.
