Victims would bring cash and meet suspects at a Brooklyn street corner in the evenings, expecting to purchase iPhones in bulk, but were robbed instead. Police say thousands of dollars worth of valuables and cash were stolen.
Undercover officers answered one of the ads and met with the suspects Wednesday evening.
They say the suspects were arrested on charges of conspiracy to commit robbery and were found with a loaded 9-mm pistol.
A call to Craigslist officials was not immediately returned.
