Suffolk County Police say 46-year old Frank Dawson and 44-year old Towania McCrae stole the oil from storage tanks on the property of eight vacant homes in the Mastic area.
On Saturday night, officers say they observed the two pumping heating oil from the underground tank of an unoccupied home on Hampton Ave. in Mastic and transferring the oil to three storage tanks that they were carrying in the rear of Dawson's pickup truck.
After the officers placed both suspects under arrest, police say Dawson took the officers to seven other locations in Mastic where he had previously stolen home heating oil.
The two are charged with Petit Larceny and Possession of Burglar's Tools.
Dawson is also charged with Criminal Trespass 3rd Degree.
