Music maestro Ilayaraja suffered a mild heart attack while working at his studio in Chennai on Monday morning. The 70-year-old legend is currently undergoing treatment at a Chennai hospital. Sources say his condition is stable.

Ilayaraja, 70, fondly addressed as 'maestro,' was likely to undergo an angioplasty procedure, sources said, adding, he has been advised rest for a few days.

He was, however, stable, they added.

Ilayaraja's latest work, 'Thalaimuraigal' (Generations) had hit the screens recently, earning critical acclaim for the movie's plot and the composer's tunes.

National award-winning Ilayaraja has produced some of the biggest musical hits of Tamil cinema for actors including veterans Rajnikanth and Kamal Haasan, and has worked with top filmmakers spanning nearly 40 years including Maniratnam and Gautham Menon.
