Tennis great Boris Becker could be jailed for transferring hundreds of thousands of pounds from his business account after his bankruptcy.
The six-time grand slam champion was found guilty of four charges under the Insolvency Act by a jury at Southwark Crown Court in London on Friday.
The charges include removing property, two counts of failing to disclose estate, and concealing debt.

Judge Deborah Taylor released Becker on conditional bail ahead of sentencing on April 29, when he could face a jail sentence carrying a maximum term of seven years for each count.
The 54-year-old three-time Wimbledon champion told a jury his $US50 million ($A67 million) career earnings were swallowed up by an expensive divorce from his first wife Barbara Becker, child maintenance payments, and “expensive lifestyle commitments”.
The German superstar, supported in court by partner Lilian de Carvalho Monteiro and eldest son Noah, said he was “shocked” and “embarrassed” when declared bankrupt on June 21, 2017 over an unpaid loan of more than Stg 3 million ($A5.2 million) on his estate in Mallorca.
Becker, who has lived in the UK since 2012, said he had co-operated with trustees tasked with securing his assets, even offering up his wedding ring, and relied on the advisers who managed his life.
The court was told the BBC commentator received 1.13 million euros ($A1.7 million)) from the sale of a Mercedes car dealership he owned in Germany, which was paid into a business account used as his “piggy bank” for personal expenses.
He was found guilty of transferring hundreds of thousands of pounds to other accounts, including those of his ex-wife Barbara and estranged wife Sharlely “Lilly” Becker, the mother of his fourth child.
Becker also spent 48,000 euros ($A70,000) on an ankle operation at a private clinic, paid 12,500 euros ($A17,500) to a private jet company, and splashed out 6,000 euros ($A9,000) at a luxury golf resort in China.
He was also convicted of failing to declare a property in Germany, and hiding an 825,000 euros ($A1.2 million) bank loan and shares in a tech firm.
He was acquitted of a further 20 charges, including nine counts of failing to hand over trophies and medals from his tennis career.
He told jurors he did not know the whereabouts of the memorabilia, including two of his three Wimbledon men’s singles trophies, including the 1985 title that catapulted him to stardom aged 17.
The other prizes were his 1992 Olympic gold medal, Australian Open trophies from 1991 and 1996, the President’s Cup from 1985 and 1989, his 1989 Davis Cup trophy and a Davis Cup gold coin which he won in 1988.
