Crimestoppers is to lock up company bosses in a real prison to raise £130,000.
The first Lock Up Your Boss fundraising campaign asks employees to sponsor their managers to experience one night behind bars in Peterborough.
An entry form was mailed to 2,000 employers, mainly in the Peterborough area, asking entrants to raise a minimum of £2,000 to guarantee a berth in one of 65 cells in the new prison on 10 March. The prison will be prepared for more traditional purposes three weeks later.
Crimestoppers chief executive Michael Laurie will lead the way, with his counterpart at the Camelot Group, Dianne Thompson, among 15 business leaders, senior police officers and TV actors already signed up.
Champagne and canapes will help make the experience bearable, though a Crimestoppers spokeswoman insisted: "There won't be much luxury." She said inmates would endure a "brief but entertaining version of the prisoner initiation procedure" before experiencing the "lingering effect of the cell door banging shut and being locked up".
