Police arrested a man allegedly involved last month in an armed robbery in which employees were tied up at a Radio Shack in Wahiawa.

Two men, ages 21 and 24, entered the business and restrained the employees about 8 p.m. June 8, police said. One man brandished a handgun and the two robbers ran off with merchandise and cash.

Detectives identified the robbers and one of them was arrested Wednesday morning for investigation of first-degree robbery, kidnapping, and use of a firearm in a felony.

The man was released pending investigation.
