Police arrested a 24-year old man suspected of holding up a Mililani woman who was trying to sell her Ipad on Craigslist. The 23-year-old woman met the suspect and three other men on Ikuone Place in Makaha at 6:30 a.m. Monday. The suspect asked to see the Ipad before buying it and when he got it, he allegedly pulled out a gun and he and the others took off. He was arrested later at a 7-11 store on first-degree robbery charges.
