Korea's industrial production, retail sales and facilities investment all declined in April from the previous month, data showed Friday, raising further concerns over a potential slowdown of Asia's fourth-largest economy.

Industrial production went down 0.8 percent last month, reversing modest gains posted in March, according to the data compiled by Statistics Korea.

Retail sales, a gauge of private spending, dropped 0.9 percent from a month earlier in April.

Facility investment also saw a decline, falling 0.4 percent from the previous month.

It marks the first time since January — and the second since October last year — that all three major economic indicators declined simultaneously.
