From today's Guardian:

A year on, we still wait for answers about Ian Tomlinson's death

It has now been one year since the tragic death of Ian Tomlinson during the G20 protests in the City of London on 1 April. While we appreciate a fair and thorough investigation takes time, Ian's grieving family has been left in limbo for a year waiting for a full explanation about the circumstances of his death. There is now very real concern as to whether the Crown Prosecution Service (CPS) proposes to charge anyone in respect of the assault and death of Ian.

The CPS has been in possession of the provisional Independent PoliceComplaints Commission investigation findings since August 2009. We understand that these findings, at least in part, will provide the basis for a decision on whether to prosecute anyone for Ian's death. We also note that the director of public prosecutions said in a Guardian interview (21 September 2009) that he hoped the CPS would reach a decision "within a few months".

Delays in the investigation and charging decisions increase the suffering for families of victims leaving them unable to gain closure and move on with their lives. Families are greatly concerned not to prejudice the process and are therefore effectively silenced from expressing their views publicly about the death of their loved one. They are desperate to ensure any potential future legal proceedings are not undermined nor an excuse found to abandon any cases that might be brought. The Tomlinson family has endured a year of public scrutiny unable to respond to questions about Ian's death, with little they can do but wait for the outcome of a decision. The delay however is now intolerable.

The policing of the G20 protest caused widespread public concern around use of excessive force by police officers. Proceedings against many protestors arrested on the day, as well as a number of reviews and investigations into the events of the day, have all been concluded. In the case of Ian Tomlinson, there is a heightened need for the statutory investigating body to be seen to be carrying out justice in a robust, transparent and timely manner to address public confidence. One year later the public, like the Tomlinson family, are still left with unanswered questions about how and why Ian died at the G20.

In the absence of any updates from the CPS, we have growing concerns about the investigation into Ian's death. There has been a complete lack of communication and transparency about the delay into concluding the investigation into Ian's death that calls the CPS's credibility into question.

As we have already set out, we do not wish to prejudice any investigation or potential proceedings but believe that either a decision or public explanation is due. We call on the CPS to fulfill its public duty regarding the investigation into the death of Ian Tomlinson.
