Police say the clerk caught up with Alma Cline of Wilmington at the exit and she handed over the gun, which turned out to be a pellet gun, then fled.
A police dog tracked Cline to a home two blocks away, where troopers could see her sitting on a sofa inside.
Cline was arrested and charged with first-degree attempted robbery. Police say Cline was wanted on a burglary warrant from Elsmere Police. She's being held on both charges at the Women's Correctional Institute on $7,500 bail.
