NAPLES, Fla. - Naples Police arrested Ob Akeem Arnold after a robbery where his own brother worked, at the CVS Pharmacy on 9th Street South, just before midnight.

Investigators said Arnold's brother was taking out the trash at the time. That's when Arnold came up from behind and ordered him into the building against his will. Arnold allegedly forced him to take out more than $1,400, then tied his brother's hands and feet, leaving him in the office.

Witnesses inside the CVS say they heard it all while shopping. Only WINK News was on scene when police officers counted the money the suspect took from the register.

Police used dogs to sniff out the suspect.

Arnold was arrested for Robbery, Kidnapping, Aggravated Battery, Battery on LEO, Obstructing Justice, Use/Display Weapon During Felony, Grand Theft, Resist Officer With Violence, and Commit 3rd degree Felony Wearing Mask. He remains behind bars.
