A 17-year-old and 20-year-old were arrested Thursday with a note in their pocket threatening to harm an east side Walgreens' employees if they weren't given pills.
If they'd succeeded, it would have been the store's third robbery this week.
Lawrence police detectives were conducting surveillance on the Walgreens Pharmacy at 4555 N. Shadeland Avenue Thursday when they saw two males matching the descriptions of previous robbery suspects entering the business.
Employees also saw the men, and recognized them from a previous robbery attempt on Tuesday.
When employees made it clear they saw the suspects, police said the pair tried to flee the area. That's when detectives moved in and arrested them, allegedly finding the note in the pocket of the juvenile suspect.
The juvenile suspect and the 20-year-old, identified as Timothy Woods, were taken into custody on preliminary charges of attempted robbery, a level 5 felony.
Lawrence police were working with detectives from other agencies to see if the pair could be connected to other recent robberies in the area.
