Not the world famous United States Central Intelligence Agency, but a group of Thai street food carts.

They've earned the nickname for the intelligence they gather ahead of Thailand's ongoing anti government street protests so they can rush to sites to hawk their dishes.

The so called CIA used their cell phones to study announcements by demonstrators who usually announced protest site to the last minute to confuse police.

When they find out the location, they could then quickly reach the site not only ahead of police but before many protesters themselves way have to follow the news very closely, this vendor says.

The street food hawkers sell everything from fish balls and fried chicken to dim sum and ice cream.

With tens of thousands of demonstrators in attendance, business is booming.

This'll vendor says he makes about 162 $192 each time.

Protests first began in July against Prime Minister Prayut Chan O Cha, Thailand's former military ruler.
