DARIEN — Approximately $600 of cooking oil was taken from a container behind Jimmy’s South Side Tavern.

Police were called to the Heights Road restaurant Sept. 5 at 3:40 p.m. after an employee of the company purchasing the oil found the lock on the container cut. The grease had been taken out of the container. The employee told police this was happening at other client locations and the grease is often stolen in the early morning hours.

Cooking oil is often sold on the black market because it is used for biofuel. Trade group the National Renderers Association estimates that $75 million worth of the stuff is stolen across the country every year.

Police searched the area, but didn’t find any evidence or suspects. Investigation is ongoing.
