An apologetic robber stole about $100 at gunpoint from a 7-Eleven store at 2458 Delaware Ave. this morning, Northwest District police said.

The store clerk told police that the robber entered the store shortly before 11 a.m. and pulled a black pistol from the left side of his waistband. She told officers that the robber said, “I’m sorry I have to do this. Give me the money in the register.” The clerk surrendered about $100 in small bills, and the gunman fled north on Delaware Avenue, police reported.
