Handling of G20 protests were "proportionate", police chiefs say
A fourth independent inquiry has been launched into claims of police brutality during G20 London protests.
A woman claims she was assaulted during a "kettle" control tactic deployed by officers, the Independent Police Complaints Commission (IPPC) said.
There are three other G20-related inquiries taking place, about the death of newspaper salesman Ian Tomlinson, and the alleged assault of two women.
Police chiefs have said the handling of protests was "proportionate".
However, the practice of holding protesters in "kettles" has been criticised.
The latest investigation is into an alleged assault as police contained a group in an alleyway in the Bishopsgate area on 1 April.
Overall, the IPPC has forward 131 complaints to the Metropolitan Police.
The total number of G20-related complaints made to the IPPC was 276.
Speaking back in April, Sir Ken Jones, president of the Association of Chief Police Officers, said the policing of the G20 protests in the UK was "proportionate" and recent criticisms had lacked objectivity and perspective.
