Police say a pair of teenagers, one suspect and one cashier, tried to work together during a robbery at a grocery store in Franklin Township.

Police responded to a call reporting an armed robbery Saturday around 7:30 p.m. at a grocery store on Route 27.

According to police, Cameron Smith, 19, of Somerset, passed a note to a 17-year-old male cashier demanding all the money in the register, and left with the cash.

Police say the note said the suspect had a gun, but no gun was ever shown. 

But during the investigation, police discovered the pair knew one another, and their plan was to split the cash.

Both have been charged with theft.
