SAN DIEGO -- A Mission Valley man has been arrested on suspicion of armed-robbery in connection with three holdups of people trying to sell Apple iPads on Craigslist this week.

San Diego police arrested Keith Randall Smith, 34, at his home Wednesday, SDPD Lt. Andra Brown said.

The first of the robberies occurred about 9:30 p.m. Sunday, when Smith allegedly pulled a gun on an iPad owner at the victim's Talmadge apartment, stole the tablet-style computer and fled, Brown said.

The other two holdups played out in similar fashion the next night, according to police. The first occurred about 8:30 p.m. in the backyard of a Mount Hope woman's home, and the second roughly 90 minutes later, near another victim's Corridor-area residence.

During the first and third robberies, the thief was accompanied by an accomplice described as a thin, roughly 5-foot-4-inch blonde in her early to mid-20s, wearing a hooded sweat shirt and dark-colored pants. She remained unidentified and at large this evening.

In each case, the bandit was responding to a for-sale notice placed on the Craigslist classified-ad website, according to Brown.

At the time of Smith's arrest, detectives recovered two of the stolen iPads along with the pistol the suspect allegedly pulled on the victims, the lieutenant said.

Smith was being held in county jail on $50,000 bail pending arraignment, scheduled for Friday afternoon.
