Law enforcement officials in Tippecanoe and Boone counties are searching for three suspects in a robbery and attempted robbery early Monday morning. Lafayette police reported that three black men entered a Speedway Gas Station at 4325 State Road 26 East just after 2 a.m. and showed the clerk a gun. They took an undisclosed amount of cash and fled. About an hour later, thieves matching the same description attempted to rob a Circle K on State Road 334 in Whitestown, but were unable to leave with money, according to the Boone County Sheriff’s Office. The suspects were seen leaving both locations driving a black, two-door Pontiac Grand Am with custom wheels.
