*677 - can anyone verify/debunk this email?

Another chain email I received at work. I suspect this is BS all around. But is any of it true?
> MUST KNOW *677
>
>
> I knew about the red light on cars, but not the *677.
> It was about 1:00 p.m. in the afternoon, and Lauren was driving to
> visit a friend.
> An UNMARKED police car pulled up behind her and put his lights on.
>
> Lauren’s parents have always told them never to pull over for an
> unmarked car on the side of the road, but rather to wait until they get
> to a gas station, etc.
>
> Lauren had actually listened to her parents advice, and
> promptly called 677 on her cell phone to tell the police dispatcher that
> she would not pull over right away.
> She proceeded to tell the dispatcher that there was an unmarked police
> car with a
> flashing red light on his rooftop behind her.
> The dispatcher checked to see if there were police cars where she was
> and there weren’t, and he told her to keep driving,
> remain calm and that he had back up already on the way.
>
> Ten minutes later 4 cop cars surrounded her and the unmarked car
> Behind
> her.
> One policeman went to her side and the others surrounded the car behind.
> They pulled the guy from the car and tackled him to the ground.
> The man was a convicted rapist and wanted for other crimes.
>
> I never knew about the *677 Cell Phone Feature,
> but especially for a woman alone in a car,
> you should not pull over for an unmarked car.

> Apparently police have to respect your right to keep

> Too bad the cell phone companies don’t generally give

>
> Speaking to a service representative at Bell Mobility confirmed that
> *677 was a direct link to OPP Dispatch.
> So, now it’s your turn to let your friends know about *677.
