Officers arrested and booked a Hammond man with extortion in connection with activities that a woman accuser said began on Facebook, the Hammond Police Department reported Tuesday.

After meeting a woman on the social network, Adam David Kolb, 26, is accused of calling the woman, allegedly having sexual relations with her and eventually threatening her, said Lt. Vincent Giannobile.

Kolb came into contact with the woman by pretending to be a woman on Facebook himself, according to the police spokesman.

Kolb allegedly called the woman and told her he was a friend of the woman he was pretending to be on Facebook, Giannobile said.

“We did some investigating though Facebook” and talked to other women with whom Kolb has had contact, the police spokesman said late Tuesday.

Other women with whom Kolb had Internet contact are being interviewed, but determining what has transpired may be a time-consuming process, Giannobile said.

Some of Kolb’s other contacts are from Tangipahoa Parish — particularly the Hammond, Ponchatoula and Independence areas, Giannobile said.

Giannobile said Kolb has lived in other areas, including Kenner.

“We don’t know how many times this has happened,” the police spokesman said. “It’s an ongoing investigation.”

He said the woman who has accused Kolb of extorting her contacted the Hammond Police Department last Friday.

After beginning an investigation, officers arrested and booked Kolb into the Hammond jail Monday night, Giannobile said.

Kolb remained in jail in Hammond Tuesday evening. Officers said he was awaiting transfer to the Tangipahoa Parish jail.
