Petrol bombs thrown at police van in Enfield
Two petrol bombs were thrown at a police vehicle during a routine patrol in north London where riots took place.
The missiles landed near the marked police van at about 23:30 BST on Wednesday at Fore Street in Enfield.
A police spokesman said: "Officers became aware of what appeared to be petrol bombs landing near the vehicle".
The officers in the vehicle were unharmed and there was no damage to the vehicle itself. No-one has been arrested over the attack, police said.
Trouble broke out in Tottenham, north London, on 6 August following a peaceful protest over the fatal police shooting of Mark Duggan.
Looting and violent disorder then spread to Enfield and other parts of London, with the worst of the rioting seen on the night of 8 August.
Several shops and businesses were attacked in Enfield and the Sony Distribution Centre on Solar Way was burnt down during the riots.
