Like the man who told us 2.4 million followers on Instagram that he had a cure for Corona virus.

He was just arrested after the FBI says he tried to sell them pills in an undercover operation.

Les Trent has details.

My name is Keith Middlebrook.

This man is making the unbelievable claim that the syringe he's holding can cure the Corona virus.

This is the cure right here, going into mass production.

And this is going to save and change the world.

Is he a doctor?

A scientist?

Nope.

53 year old Keith Lawrence Middlebrook is a bit actor.

He had a cameo in Iron Man two.

I have what makes you immune to the Corona virus.

Not so fast.

The FBI just arrested him for attempted fraud.

He isn't the only alleged scammer out there.

The FBI says thousands of Americans are getting bogus robo calls like this.

If you want to receive a free testing kit delivered overnight to your home, this Florida retiree says to scammers, actually came knocking on his door, offering a Corona virus test for $300.

They should be ashamed of themselves.

I hope they catch them.

Morris.

You Mansky called 911 that the people that came to my door yesterday that he wants to be a Corona virus.

It's a scam.

I knew it is scam.

I'm 72 years old, but I didn't.

I wasn't born yesterday.

Our investigation also found ads offering test kits all over the Internet.

We paid $600 for 30 of these Corona virus home testing kits.

Guess what?

They never arrived.

Obviously, a complete scam.

North Carolina Attorney General Josh Stein is vowing to shut down anyone selling unapproved test kits.

It is wrong to exploit people's desperation to make a quick buck.

The company that makes those test kits, bio medics, tells us that's not their ad or their product.

On Craigslist, they tell us they sell on Lee toe authorized distributors, clinical professionals and government agencies for FDA guidelines.
