India's cricket chief Sourav Ganguly was taken to hospital with chest pain on Wednesday, nearly three weeks after being discharged following a heart operation.
The 48-year-old former captain suffered a heart attack early this month and underwent a successful angioplasty operation in his hometown Kolkata.
"Ganguly was rushed to Apollo Hospital after he experienced chest pain and uneasiness on Wednesday afternoon," Manotosh Panja, a senior doctor, said.
The left-handed opener retired from Test cricket in 2008 having accumulated 7 212 runs including 16 centuries - his first made at Lord's on debut.
He also scored 11 363 runs in 311 one-day internationals.
