INDIANAPOLIS -- A fire at a Citizens Gas and Coke utility plant on the city's near east side caused authorities to restrict traffic in the area Wednesday morning.

Officials said a piece of equipment caught fire just before 6 a.m. at the plant, located in the 2900 block of Prospect Street. An internal fire department and the Indianapolis Fire Department responded, and the fire was under control by 7 a.m., officials said.

The fire was confined to the the area of the equipment, which removes impurities from gas during the process of baking coal into coke, an official said.

No injuries were reported. Citizens Gas said the fire poses no health concerns for people in the area.

Authorities restricted traffic near the plant between Sherman and Keystone.

Flames were shooting into the air from several points at the plant, but the company said most of the flames represented an attempt to burn off some of the gas in a line affected by the equipment fire. Company spokesman Dan Considine said the controlled burns would happen for much of the rest of the morning.
