Underground blasts fire Indianapolis manhole covers into air

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.
