In the last few days Indianapolis thieves have made off with dozens of hefty manhole covers and sewer grates.

The missing manhole covers have left gaping holes throughout streets across the city.

Margie Smith-Simmons, a spokeswoman for the city's Department of Public Works, says, "This is a severe public safety hazard we have here, these manholes range in depth from 4 feet to 30 feet deep."

Local officials believe the high price of steel is driving the unusual items being stolen.

They believe the thieves mot the price for a ton of scrap steel going from about $70 to $300.
