The cousin of British singer Leona Lewis has been sent to prison “indefinitely” on Friday (July 22).

Adrian Henry has been jailed for taking part in an armed robbery on the Omega Sauna in Kentish Town, London in January 2009.

The 29-year-old previously served 12 years in a young offenders institution after taking part in the gang rape of an Austrian tourist when he was 14 years old. 

Leona has said about her extended family, "There are bad people in my family, but we didn't really mix with them... I saw the pain that someone else's badness caused for other people. You have to think and make your own mind up."
