A supermarket employee spotted people stealing used cooking grease from Big Y in East Windsor Thursday morning and police said they have arrested three suspects.
Police said an employee of the market called them at 5:50 a.m. to report three men in a white van with a New York registration were siphoning used cooking grease from a container at the back of their building.
She said she told the men they were stealing, but they ignored her, quickly packed up their siphoning hose and left the parking lot.
Police officers got onto Interstate 91 South from exit 44, spotted the van approaching exit 38 in Windsor and stopped it.
As officers approached the van, they saw grease leaking from the vehicle, police said.
The people in the van, all from Yonkers New York, had no identification and were detained, arrested and charged with conspiracy to commit larceny in the sixth degree and sixth-degree larceny.
Police said they found two large drums with 450 gallons of used cooking grease in the van. It was estimated at a value of around $500.
