INDIANAPOLIS (AP) — Electrical arcing in cables is being blamed for underground explosions that shot manhole covers into the air at a busy downtown Indianapolis intersection.
Indianapolis Power & Light officials said Thursday that the arcing caused short circuits and left the utility's infrastructure with "significant damage."
No one was injured, but hundreds of customers remained without power mid-day. Senior vice president of customer operations Joe Bentley said some outages would continue into the evening.
More than a dozen similar incidents have occurred over the last decade. The utility has replaced about a third of its downtown manhole covers with ones that lift only a few inches in cases of explosions.
City officials say they will work with the utility to ensure safety ahead of next month's men's Final Four basketball tournament.
