Andrew Calvert is back behind his desk today after being locked up in the name of charity.

The Western Newspapers managing director, whose titles include those at Bath Newspapers, Clevedon Newspapers, Mid Somerset Newspapers, Taunton Newspapers and the Western Gazette, was threatened with "arrest" if he didn't raise £500 for the Royal United Hospital Bath's Forever Friends appeal.

Thanks to the generosity of his friends and colleagues, he actually managed to raise £850 for the appeal – but he was still detained by police who saw through his fiendish disguise as Herr Doktor Otto von Hildegard.

Andrew said: "I attempted to avoid arrest by adopting a clever disguise and even placed a notice on my office door to throw them off the scent.

"However, the police were too clever for me and were able to unmask me with little trouble.

"I would like to thank all my friends and colleagues who gave so generously to the appeal."

The Forever Friends appeal is aiming to raise £10m for diagnostic and treatment equipment for the hospital's cancer, cardiology, children and critical care units.
