Cops: World's oldest job goes high-tech

ARLINGTON, Texas (KXAS/NBC) - Police said the world's oldest profession has gone high-tech.

More prostitutes are leaving the street corner and turning to the Web.

"What we are seeing is just outright advertisements for sexual services," said Arlington Police Department Deputy Chief Jaime Ayala.

On one Web site well-known for its "adult services" advertisements, one out of every five ads in Dallas-Fort Worth originates in Arlington.

"We have received a number of complaints about what appears to be obvious postings of what appears to be prostitution," Ayala said.

The Arlington Police Department is now launching operation "You Never Know" to fight online solicitation.

Undercover officers will be surfing the Web, posing as prostitutes and "Johns."

"If you respond to an ad or place one, you never know who might be on the other end of the line," Ayala said.
