Mumbai : India’s industrial output grew a weaker-than-expected 0.1% year on year in April, official data showed on Tuesday, amid growing concerns about a slowdown in the economy.

The manufacturing sector, which accounts for most of the industrial production index, expanded 0.1%, with production of capital goods, a key indicator of investment, shrinking 16.3%.

Analysts had expected output to grow 1.7%. The April figure compares with an annual contraction of 3.5% a month earlier.
