Ahmed looked the part of a deal maker.
"He was Prada and Gucci from head to toe," Weinberg said. "He was a nice guy, but he also had a bit of an edge and arrogance about him."
It all looked like a good deal for everyone, and later that day, Weinberg and the rest of the team signed a contract at the offices of Karmic Management, one of three Los Angeles-based companies assigned to handle entertainment, public relations and sponsorships for the Bieber project.
But only Weinberg put up money.
Weinberg said he paid $860,000 to Ahmed to secure the concert venues and $140,000 to Karmic Management to get a website created and for other parts of the deal.
Ahmed sent Weinberg a text that the bank had confirmed the wire transfer of funds and said, "I just got a call from President Obama's election campaign since I am the chair for Norway so they need me in Chicago today, so heading over there now."
At that point, Weinberg said he thought the deal was on.
"After I invested the money, there was a lot of friendly collaborations happening," Weinberg said. "A lot of e-mails coming back and forth. Waleed was very involved and we started talking about who our ticketing agency was going to be, which was an organization that everyone has heard of. ... We hired a company to start developing a website for the Scandinavian leg of the tour."
But it wasn't long before, as Weinberg put it, "a couple of things went off track."
Conning the con man
First, Weinberg said he started getting nervous when Ahmed "went off the radar" for 10 days.
"Well, you can imagine after 10 days, we are freaking out," Weinberg said. "Something is not right. Well, he surfaces and tells us, 'I'm sorry, you know, I was basically out for a Muslim holiday. I was out for Ramadan, and I'm sorry, but I am back. Let's go.' "
Around the same time, Weinberg said he began to hear about problems with the company handling the ticket sales. Then, Ahmed appeared on a radio interview in Norway, talking about his latest clothing purchases.
"Shoes, jacket, I have more at home," Ahmed told NRK reporter Webjørn Espeland. "I was in the U.S. and shopped Louis Vuitton for approximately 60,000 NOK (Norwegian kroners)."
That's more than $10,000 in clothing.
The next week, Ahmed returned to the United States. Weinberg got on a plane and met him in New York for dinner.
"This whole thing was disturbing and extremely confusing. He was talking in circles, and nothing was adding up," Weinberg said.
Then, the ruse came to an abrupt end when Weinberg learned that tickets for Bieber's Scandinavian concerts went on sale and quickly sold out.
"We couldn't believe it," Weinberg said. "We never had the deal. So this is when all of the alarms started going off, of course. And that's when Waleed got really squirrelly and became very hard to reach."
Weinberg had had enough. He contacted the FBI.
Meanwhile, Ahmed was in Norway in late September. During that trip, he posed for photos to accompany the radio interview he had given to Norway's NRK.
He would then make a fateful decision to return one last time to the United States. Weinberg persuaded him to meet at a restaurant in San Francisco.
They sat in a booth near the front door. Weinberg wore a wire, recording the conversation for the FBI.
"For two hours, Waleed goes into this whole dissertation about how his life is over as he once knew it," Weinberg said. "The Waleed Ahmed of Norway, the Mark Zuckerberg, the celebrity, the guy that everybody was excited about has now become a disappointment."
Ahmed explained to Weinberg how his parents have disowned him, and how he is in such financial straits that he's going to lose his home -- even his new Porsche. He said he planned to start his life over in Pakistan, where he has an uncle in the real estate business.
