A 21-year-old man who was arrested allegedly with tools in his waistband has been charged in connection with the robbery of a Stickney bank last week, according to the federal complaint.

Isa Allan, of Countryside, is accused of demanding money from a teller at the U.S. Bank branch located at 4001 S. Harlem Ave. during the May 9 robbery, according to the complaint.

Allan was arrested shortly after the alleged robbery with a hammer and drill in his pants, according to the complaint.

Authorities allegedly recovered $7,460 from his stolen vehicle and a note from the floorboard that read “Give it all, don’t scream, don’t make a scene, no dye packs, no GPS, big bills. I will kill you,” according to the complaint.

A man wearing a blue baseball hat and glasses walked into the U.S. Bank location at around 10:15 a.m. and handed the threatening note to the teller, according to the federal complaint.

The robber then told the teller “I’m watching you, stay quiet,” before the teller handed over the cash, according to the complaint.

According to the complaint, the man demanded more money each time the teller retrieved cash from the drawer. After the teller emptied the drawer, the robber fled the bank with the cash stowed in a bag.

The teller immediately alerted coworkers after the incident and police were called, according to the complaint.

Stickney officers responded within minutes and spotted a man matching the description of the robber standing next to the open door of a van, according to the complaint.

The man ran and was arrested by police after a brief pursuit, according to the complaint.

Allan allegedly gave police a fake name before police determined his true identity, according to the complaint.

The van belonged to a construction company and had been allegedly stolen earlier that morning while parked at 400 block of South Dearborn Avenue in Chicago, according to the complaint.

A teller from the bank allegedly was able to identify Allan as the robber, according to the complaint.
