ROGERS PARK — Police say a Chicago man robbed a Subway sandwich shop with a knife, and then crossed the street and bought a sandwich at Subway's competitor, Potbelly, where he was arrested.
Fredrick Warren, 43, was still eating his Potbelly sandwich when police arrived just before 5 p.m. on April 26, police said.
About 20 minutes earlier, Warren had walked into the Subway at 6449 N. Sheridan Road and held up the cashier with a folding knife, police said.
A customer who walked in mid-robbery told investigators she saw Warren leaning over the counter and grabbing cash from the register, police said.
Investigators caught Warren's trail by watching Loyola University Police surveillance video, according to Chicago and Loyola police departments.
It showed Warren walking south down Sheridan Road, crossing the street and then walking back north to Potbelly at 6464 N. Sheridan Road, police said.
There was no sign of him leaving the Potbelly, so they went inside and found him eating near the back of the shop, his gold coat draped over his seat, police said.
He was arrested — and police found $186 in cash and a silver-bladed folding knife with a black handle on him, police said.
Warren, of the 2300 block of East 75th Street, was charged with armed robbery.
