West Suffolk College principal Nikos Savvas was arrested and locked up in a police cell — to raise money for a local hospice.
Police handcuffed Mr Savvas in his office before leading him to a police van outside.
He was driven to Bury St Edmunds Police Investigation Centre, where officers took his fingerprints and a mugshot before locking him in a cell for around an hour.
Mr Savvas was released after handing over around £700 to St Nicholas Hospice Care, in Bury St Edmunds.
The money had been raised through his JustGiving internet fundraising page and a bucket collection around the college.
He said: “Being arrested, even in fun, was a sobering experience. The high security police investigation centre is a very harsh environment and the microwaved all-day breakfast I was given was a punishment in itself.”
Mr Savvas was one of a dozen people arrested as part of a fundraising event, called Jail and Bail, for the hospice.
