The owner of Rawley's Hot Dogs, 1886 Post Road, called police Monday afternoon to report that a neighbor had told him that two men were seen pumping grease from the eatery's grease storage bin at the rear of the building.

The owner was not sure how much grease was siphoned off, but told police he believes the men may be the same pair seen stealing grease from the bin in the past.

The recycled cooking oil can be used as a source of fuel for converted motor vehicles.

Police are investigating.
