Victor Marke is a convicted sex offender, and former producer/director and martial arts instructor. In 2015, he married then-actress Zara Phythian, his second wife who was over 20 years younger than him, and was also convicted along with him. The couple met when he was Zara's martial arts instructor.

In May 2022, he was convicted of 14 child sex offenses and found guilty of sexually abusing a young girl, from age 13 to 15 - between 2005 and 2008, along with his wife Zara Phythian while working as martial arts instructors in the UK; Zara received an 8-year sentence. Victor was jailed for a total of 14 years, with four years of that sentence included in additional charges of indecent assault on another girl, also denied by Victor Marke, but convicted by a jury at their trial. Now on the sex offender's register for life, he is automatically barred from working with children.
