And the critical bit at the end.

Chief Constable Garry Forsyth from Bedfordshire Police in a statement says racism has no place in policing and it is an issue that is close to his heart that he is determined to tackle.

He states: "It is important that these former officers have spoken out about being subjected to racism while working for Bedfordshire Police and I'm sorry there was not suitable support in place to encourage them to stay within our organisation and continue their careers with the force."

The Chief Constable goes on to say as a force they are working hard to put new processes in place to support police officers from all backgrounds including appointing a new Chief Superintendent to look at recruitment, retention and progression but and admits there is still more to be done.
The Chief Constable says there is still more to be done. That doesn't sound like there's no problem to me.
