Leona Lewis' cousin has been jailed for six years for his role in a brutal robbery.

Adrian Henry, 27, and two accomplices broke into a north London drug den where they viciously attacked three men before robbing them on the Easter long weekend in April.

There were no weapons used in the attack.

A neighbour called the police, who found Adrian hiding under a bush outside the property in Arsenal.

He pleaded guilty to robbery at Blackfriars Crown Court last week and was sentenced to six years in prison today (07.09.09), leaving 'Bleeding Love' singer Leona "heartbroken".

Adrian's younger brother Erren, 20, was also allegedly arrested in conjunction with the robbery, but has yet to be tried or sentenced.

Leona is said to be close to both cousins, and has spoken publicly about their troubled lives in the past.
