Cleveland Police are facing more compensation claims after paying out £550,000 worth of damages to a lawyer from Middlesbrough for wrongful arrest last week.
James Watson won his case after what he described as a vendetta against him which saw him being arrested in 2009 and having his home searched.
It followed a high-profile kidnap and blackmail case and a defendant's subsequent acquittal, which led to officers investigating him for allegedly perverting the course of justice.
No charge was ever brought against James Watson.
It has emerged today that four more people involved in the case are to seek damages from Cleveland Police.
The force has received formal letters of claim from two people and notification from solicitors that two more individuals intend to pursue claims.
"I am aware of the interest in this issue but understand that legal proceedings have commenced therefore it is impossible to comment at this time.
"I hope that the IPCC will publish the report which will give a greater public understanding about what has happened."
