Kauai police Wednesday night arrested a 42-year-old Kapaa man who allegedly robbed a Kapaa pharmacy Sept. 19.

Police said the man was arrested at his home on suspicion of first- and second-degree robbery.

At about 12:30 p.m. Sept. 19, a masked man armed with what looked like a handgun, walked into the Kapaa Pharmacy and demanded prescription drugs.

The pharmacist complied, and the man fled with more than $1,000 in prescription drugs.

Police, using surveillance video, were able to identify the suspect.

He was later arrested and is being held in police custody in lieu of $500,000 bail.

The suspect has not yet been formally charged and is expected to appear in District Court next week, police said.
