Police say rioters fired gunshots at unarmed officers and a police helicopter during this month’s disturbances in the English city of Birmingham.
West Midlands Police released footage on Saturday showing masked men firing shots during riots on August 9.
The force said 11 shots were fired. Chief Constable Chris Sims called it “a concerted and organised attempt to kill or injure police officers.”
Police also said they had arrested an eighth suspect over the deaths of three men run down by a car in Birmingham as they protected shops from looters.
Four people have already been charged with murdering Shazad Ali, Abdul Musavir and Haroon Jahan.
More than 1,300 people have been charged over the riots that flared in London and other English cities for four nights.
