FARMINGVILLE, N.Y. (CBSNewYork) — Police have arrested the suspect wanted for stealing prescription drugs and cash from a Long Island drug store.

Suffolk County police say they arrested 22-year-old Patrick O’Donnell of Ronkonkoma on Thursday.

Officials say he stole oxycodone and about $200 from a CVS in Farmingville last Sunday afternoon.

Police said O’Donnell first entered the store and asked an employee if they had certain prescription drugs. He left the store, and returned later, presenting a threatening letter to the pharmacist.  The pharmacist complied and the suspect fled on foot, police said.

O’Donnell is charged with third degree robbery and is scheduled to be arraigned later today.

The incident occurred just a week after Jennifer Mejia, Raymond Ferguson, Jaime Taccetta, and Bryon Sheffield were killed at Haven Drugs in Medford during an alleged robbery.
