KANSAS CITY, Mo. -- Police are searching for crooks who held up a Fast Stop convenience store, then needed help from the clerk to open the door on the way out.

Police said two gunmen robbed the store in the 8400 block of Hickman Mills Drive Monday morning.

Security surveillance video showed two men shoving cash and liquor into a duffel bag.

As the men went to leave the store, they seemed unable to exit. The clerk had to help them open the door, because they were trying to pull the door even though the sign indicated it was a push-to-exit door.

"They can rob, but can't read," the clerk pointed out as he watched the surveillance video.

One of the men, police said, was wearing a pair of red and white motorcycle gloves. Authorities hope someone will recognize the distinctive gloves and help identify the crooks.

If you have information about the robbery, call the Crime Stoppers TIPS Hotline at 816-474-TIPS.
