Redknapp found himself in a bleak interrogation room at Chichester Police Station, in West Sussex, under arrest and being asked to remove the belt from his trousers.
"I think they were worried I'd hang myself," he said, sombrely.
When he wanted to use the toilet, he had to do so in the company of a policeman. Redknapp had his fingerprints taken, along with a sample of his DNA, before he was bailed to reappear at a police station in February.

"Lovely gestures, important to me," said Redknapp yesterday.
"This has hurt me, big time," he admitted to the Mail on Sunday. "My life has been turned upside down. If I'd done something wrong, you could kick me out of football, hang me as a disgrace. I'd have ruined not just my life, but the lives of my family. Why would I do that? There isn't enough money in the world to make me do that."
