Police believe the robbery reported at a Doctor John's store in northwest Lincoln in January was an inside job, a spokeswoman said Monday.
Shantel Stickney, a clerk at the store at 2410 N.W. 12th St., told police Jan. 11 a masked man entered the store, displayed a semi-automatic handgun and demanded money from the cashier.
He left the store with an undisclosed amount of money and thousands of dollars of sex toys, Officer Angela Sands said.
Stickney also told police the robber stole the adult novelty store's surveillance system during the robbery.
Investigators later located the surveillance system and found inaccuracies in Stickney's report.
In video pulled from the surveillance system, a vehicle pulls into the parking lot at Doctor John's and flashes its lights twice, at which time Stickney goes to the store's backroom, where the surveillance system operated from, Sands said.
As the robber enters the store, the surveillance system is disconnected, she said.
Police received multiple Crime Stoppers tips indicating this was an "inside job," she said.
Officers found a vehicle used in the robbery belonged to someone Stickney knows, and investigators recovered some of the stolen merchandise.
In February, an informant told investigators some of the plunder was dumped along a county road near Garland, and deputies who went there found numerous "sex items" taken from Doctor John's in the robbery, according to an affidavit.
Police arrested Stickney, 21, on Sunday and jailed her on suspicion of aiding and abetting a robbery.
Police expect at least one more person will be apprehended in connection with the robbery.
