Atlanta police say hundreds of people have contacted them regarding a Craigslist ad with claims that a pregnant woman wants to trade her unborn child for money or drugs.

Atlanta police say in a statement they've turned the case over to the Georgia Bureau of Investigation, which is trying to determine whether the offer is real or fake.

GBI spokeswoman Sherry Lang tells WSB-TV the agency isn't sure whether the ad is a hoax, but that is a "definite possibility."

The ad claims to be from someone six months pregnant, but "don't want it" and willing to "trade it for $ or drugs."

Atlanta police said in a statement on the department's official Facebook page that the ad is "highly disturbing and suspicious" but no law has been broken yet.
