COLLIER COUNTY, Fla.- A scary scene unfolding at CVS near Downtown Naples Wednesday night. And only WINK News has exclusive video of police investigating the crime. Officers said a store manager, David Arnold, was taking out the garbage when his brother Ob Akeem Arnold, wearing all black and a white mask, forced David to take him to the money. Two sisters inside the store heard the whole thing.

"We heard gimmie all you got and we heard please dont hurt me and then my sister and I realized they were being robbed so we ran to the front of the store and we told the employee to call the police and she did."

Police said Akeem Arnold hit David over the head with a hose nozzle, demanding money, while David pleaded for his life. Arnold then tied his brother up with plastic saran wrap. The whole time the victim did not fight back, something detectives said was a smart move.

"Yeah absolutely, there's no reason at all to fight for this your life is more important than anything material that cant be replaced."

WINK News asked, but investigators do not think this was an inside job. Akeem Arnold rushed out of the store with $14,000. WINK News has exclusive video of all that cash which police later recovered when they arrested Arnold.

"As soon as he busted out that side door running our K9 officer saw him," said Lt. Barkley.
