A week after Peter Hodson was fired by the Vancouver police for allegedly dealing drugs, the man who says he launched the investigation into the officer has come forward with his story.

Tyson Pappas is a convicted drug dealer who's been in and out of jail. He alleges that he was recruited to sell for Hodson.

After what he describes as an alarming run-in with Hodson in a Downtown Eastside rooming house, Pappas says he decided to turn to the police.

At a press conference last week, Chief Const. Jim Chu announced that he had fired Hodson after an investigation revealed evidence that he was dealing marijuana on and off the job.

The former constable has been charged with trafficking drugs, two counts of breach of trust -- one for selling drugs and the other for illegal use of a police database -- and break and enter with the intent to commit extortion.

A deal is made

Pappas said the two men met at a Burger King on Main Street.

He claims Hodson had run a background check on him, and made him an offer.

"He goes, ‘You've got a raw deal in life, your cards have been dealt pretty bad. He goes, ‘I have an idea -- maybe I can help you,'" Pappas told CTV News.

"He goes, ‘Would you be interested in selling weed for me? Marijuana?'…. It took me a step back. I was surprised. He was off duty at the time but still, I knew him as a man in blue, and I thought to myself, ‘Whoa, where is this coming from ?"

Pappas claims he agreed to the deal, and some time later, a fridge was delivered to his home.

"I take the fridge upstairs, open the fridge, pull out a bag, and there was a half pound of weed," he said.

While Pappas was dealing pot, he was arrested and his drugs were seized.

He says he later lied to Hodson about how much weed he lost in the seizure so that he wouldn't have to pay.

"I thought things were okay. Then later on, I get a text message saying, ‘You little [expletive]. You lied to me. I've treated you good. I read your file,'" Pappas said.

"Then I got creeped out."

The partnership goes sour

Pappas says he decided to tell the Vancouver Police Department what was going on after an incident at his downtown Eastside rooming house.

It's alleged that Hodson snuck into Pappas's ground floor suite though a window, and demanded money.

"Enough's enough, because I was scared if I go out on the street and he sees me, I would be put in handcuffs, thrown in a paddy wagon, and nobody would see me again," Pappas said.

He agreed to wear a wire, and officers allegedly watched and listened during several meetings between Pappas and Hodson.

"We did 10 different scenarios where I bought drugs, paid for drugs. I paid money on my debt and all that. It was always VPD money," Pappas said.

He claims he was paid $1,000 and promised another $4,000 at the end of the case.

Hodson's lawyer has said he would not comment on the Pappas's story until it is broadcast on CTV News.

The Vancouver Police Department refused to discuss Pappas's role in the case, but Pappas says that if he hadn't helped, the department might never have known what was happening.

Pappas's allegations won't be tested until Hodson's case goes to trial.
