Police in Birmingham have released footage of people firing shots at lines of police officers during the riots.
The CCTV pictures also show the suspects aiming at a police helicopter.
In a press conference Chief Constable Chris Sims said events on the night of August 9 were much more complex than just looting and rioting.
He said there had been a "concerted and organised attempt" to kill or injure police officers.
The footage shows several gunmen using their weapons against the city's police force.
More than 500 people have been arrested in connection with the violence and disorder in the city so far.
Mr Sims said he had been "overwhelmed" by the support from the public but would now like them to focus on these shooting incidents and to provide information where they can.
