Less than a week after former Grand Slam tennis champion Boris Becker was freed after serving seven and a half months in a UK jail

He has spoken of his loneliness, his fears and the lessons he learned behind bars. Becker revealed how he had been attacked while in jail

In a lengthy and at times emotional one-on-one German TV interview, he revealed he had learned a hard, painful and very expensive lesson and rediscovered the person he once was

"But the whole experience also taught me something important and good. And some things happen for a good reason," he said

Becker, 55, was jailed last April for two and a half years for hiding £2.5m (€2.9m; $3m) of his assets and loans to avoid paying his creditors.

He was declared bankrupt in 2017 with debts of almost £50m because of an unpaid loan of more than £3m on his Spanish estate in Majorca.

His first weeks in detention were at Wandsworth Prison in south-west London, but most of sentence was spent at Huntercombe Prison, near Henley in Oxfordshire.
