two days later and police claim he texted at one point to tell him he could supply him with meth for sex

The mayor of one of Virginia's biggest cities supplied a detective with methamphetamine in exchange for his participation in a group sex session, according to law enforcement officials.

Mayor Scott Silverthorne was arrested outside the Crowne Plaza Hotel in Tysons Corner Thursday night after he handed a man he had met on a casual sex website 2 grams of meth.

The Fairfax mayor was under the impression that he and the man, who had known one another for a few weeks but never met in person, would be joining other men for a group party after the drug exchange inside the hotel.

Silverthorne, 50, was unaware however that the man he met online was an undercover detective with the Fairfax County Police Department, and that just a few weeks prior local authorities had launched an investigation when they received a tip that he was exchanging meth for sex.

He commented on his arrest in a Facebook post on Friday, writing: 'I ask that you allow the process to proceed before rushing to judgement (as tough as that may be).'

Silverthorne allegedly reached out to the undercover detective last month after coming across his profile online, just two days after the detective set up a bogus account.

The men began to text soon after, and during one of their exchanges Silverthorne told the detective that he could supply him with meth in exchange for sexual encounters according to police.

Soon after this is when police say that Silverthorne texted to say that he would give the detective meth if he agreed to engage in sexual activity.

The detective agreed and said he would bring other men to the group gathering. Those men were also undercover detectives.

Silverthrone showed up on Thursday at around 7pm and was taken in by police minutes later on charges of distribution of methamphetamine and misdemeanor possession of drug paraphernalia.

He was not booked into custody however and released later that night.

Silverthorne has appointed Councilman Jeff Greenfield as acting mayor at this time.

His second job as a substitute teacher for the Fairfax County Public Schools was never in jeopardy because of his arrest as his position was already terminated earlier this year.

In a press conference held Friday morning, Captain Jack Hardin of the Fairfax County Police Department said that the investigation specifically targeted Silverthorne.

'We were provided with information from a citizen that the mayor was involved with a web site,' said Captain Hardin.

'It was alleged he was exchanging meth for sex.'

He also revealed that the online profile created for the casual sex site by their detective was designed based on what they had learned Silverthrone was drawn to in a man.

Captain Hardin would not however reveal the name of the website, though he did note that while their detective was in contact with Silverthrone he was also engaging in another meth-for-sex relationship with a man he met online.

Silverthorne will be arraigned on Friday.

Detectives also found Silverthorne's suppliers Juan Jose Fernandez, 34, and Caustin Lee McLaughlin, 21, of Maryland, and arrested them.

Fernandez was charged with distribution of methamphetamine, possession with the intent to distribute methamphetamine and possession of drug paraphernalia.

McLaughlin was charged with distribution of methamphetamine, obstruction of justice and possession of drug paraphernalia.

As detectives arrested McLaughlin, police said he resisted and a detective used his stun gun. Police said there were no injuries.

All three men were taken to the Fairfax County Adult Detention Center for processing.

Silverthorne was re-elected in May for a third term of the city west of Washington after a tumultuous year in which The Washington Post reported he lost his job with the National Association of Manufacturers, filed for bankruptcy, lost his home to foreclosure and was diagnosed with cancer.

He announced in November that he'd been diagnosed with squamous cell carcinoma, and the Post said he underwent treatment that ended two months before the election.
