AC/DC guitarist leaving band for health reasons

Sydney - Legendary rock star Malcolm Young - a founding member of the Australian heavy metal band AC/DC - will not be returning to the group after taking a break due to illness earlier in the year, according to the group's official website.

The band did not reveal details of Young's illness, but said: "Unfortunately, due to the nature of Malcolm's condition, he will not be returning to the band."

Malcolm Young, 61, founded AC/DC with his brother Angus in 1973 and made it one of the most successful rock bands of all time.

The band said that a new album being released in December would be the first in their 41-year history not to feature Malcolm Young.

AC/DC are embarking on a world tour in 2015. Stevie Young - a nephew of Malcolm and Angus - will accompany them.

Malcolm and Angus were born in Scotland, but moved to Australia as children when their family emigrated.
