OK, here's the hypothetical scenario. A friend of mine has been seeing a well reviewed provider for a few years.  After one particular session with this provider, the next day my friend receives an intimidating phone call identifying themselves as LE stating the provider is under investigation and that my friend should cease and desist all contact with this person immediately.  My friends # was found on the providers phone list - this is how LE got ahold of the number in the first place. It was even suggested that my friend change his phone number and if he tries to make contact with this provider again (or she contacts him), things could get ugly - handcuffs were mentioned, family involvement, etc.  It was said many arrests were being made and if my friend did not want to be part of that, he should stop all contact.  My friend got a bit spooked - as you can imagine - and is in the process of retaining legal counsel for advice.  Did my friend "dodge" a bullet so to speak?  or could this rear it's ugly head in the future.  LE's attempt at being intimidating obvously worked.  Also, my friend is concerned about the provider and was wondering what probably happenned to her in the process.  During the converstion, it was mentioned the provider was being charged with multiple felonies (thought prostitution was a misdemeanor).

Any info or counsel would be greatly appreciated by my friend.

I would say that this is pure horse sh*t (the non-hypothetical kind.)

LE wouldn't scare you off, they would try to lure you in and bust you.  That's what they get paid for.

Here's what you do (hypothetically speaking, of course).  You ask the copper for his phone number because it's a bad time to talk and you want to call him back.

I'll lay 10:1 odds the bum will hang up or make some phony excuse that he can't give out his phone number.

This sounds like a bad practical joke or someone trying to stick it to this provider.

Prostitution is a misdeamenor most everywhere, but if she was operating a business with other gals, she could face a felony for operating a house of ill repute or some other baloney like that.  It depends on where this is.

(still not a lawyer, hypothetically or otherwise)

Ah.... Mr. Fisher to the rescue.  A few more hypothetical details about this situation.  The phone calls my friend received came from a restricted number - you might think an LE number would show up?  They did have my friend's name in addition to his number.  Also, all reviews for this provider have vanished - gone from the boards. Like I said - provider was very well reviewed and established.  Very weird.

I gotta agree, LE does not act this way.  Either they'd let you sweat and not contact or they bust you.  After the fact, it's too late to bust.  
Cops don't use slang like
"handcuffs", "bracelets", etc.  They're say you have violated city ordinance xyz and are under arrest.
I'm inclined to think some guy got hold of her phone...  BF or john grabbed her phone??  
Personally, I'd be something of a white knight and contact the lady to ask WTF?  Does she have a web site, e-mail...  you do have a anonymous e-mail right?  Or a hobby phone?  

but it is always better to be safe rather than sorry, and this provider, it would seem, has also decided the same.

(still not a lawyer)

Sounds to me like the provider might have a problem with a former SO, or possibly a stalker client.  

Your friend might consider an e-mail to the provider from his anonymous account.  He should also exercise some caution visiting the provider again if he discovers this is the issue.  These things can get ugly.

All the above post have been very helpful and have gotten me to think of some interesting scenarios as to why this situation may have occurred.  I thank you.

I would still like to seek legal counsel to have a more detailed conversation and feel it would benefit me better with someone who is familiar with the "hobby".  I reside in the New York area.  I would appreciate if an interested lawyer could contact. Obviously this would be paid advice and I am willing to do so.

You can contact me through this board or at "[email protected]"

The additional details provide hint that there is a problem of some kind.  I still don't think that LE has anything on her.  
More likely an Ex SO or stalker.  The fact her reviews are gone...  she'd decoded to so under the radar.  (If she'd been busted, they'd still be here.)  
If some stalker, ex SO or whatever there's an increased risk that some sh*t might go down that might draw you into a situation you'd not want to be involved in.
No need to contact her, since she's aware of it (in order to get her reviews taken down.)  
Since the lady is not advertizing, wants to avoid attention possibly for her safety, then your friend should respect her intention.

Well- my friend found out it was just an ex-BF trying to make trouble for the provider.  Apparently, he did a pretty good job of it.  Without going into detail, looks like calling and scaring clients wasn't the only thing he got involved with.  Thanks again for all the advice and level headed information......

Seems to me like the provider had a male friend of hers call to get rid of your friend.
Maybe she was tired of seeing him, was ready to move on and he would did not want it to end.
Not saying, that your friend is a weirdo or anything, it's just sometimes one loves more  and one takes more, then the other.

Maybe this girl was just a chicken shit and took the losers way out, hiding behind a deep seeded fear, like getting busted.

LE does no such favors.  They are here to bust people and make their lives a living hell, so they won't want to do the crime again.

They have to justify their pay.

Not hand out warnings.

I am sorry to say this, but it is more likely then not.
