A family escaped with minor injuries when a youth threw a petrol bomb at their car, writes Elaine Fogg.

The couple and their five children, aged between three and 12, were attacked at the southern entrance to Roth erhithe Tunnel on Sunday evening.

The bomb was thrown from above, cracked the windscreen, and bounced on to the road before exploding in a sheet of flame. One occupant, a boy aged nine, was burnt on the face and neck. He was treated by his family doctor.

The bomber is white, aged 16 to 18, of slim build with short, fair hair, wearing a grey T-shirt.
