The banker’s name is Joseph Carreiro, described by the Boston Herald as a financial relationship specialist at a Sovereign Bank branch in Somerville.

According to the complaint Carreiro supposedly threatened Somerville businessman William “Billy” Tauro for tickets. Since Tauro is also one of the publishers of local paper The Somerville News, this is one story that won’t go the way of yesterday’s fish wrap.

Although a district court assistant clerk-magistrate decided last week after a hearing that there were enough signs of probable cause to issue a criminal complaint, Carreiro has not been arrested. When asked about Carreiro’s status at Sovereign Bank, the Herald reports a bank spokesman answered by saying he wasn’t going to discuss the issue because “it’s a matter before the court.”

What exactly happened?

Although the venue wasn’t officially announced until the day of the performance, many rumors pertaining to where U2 would play in the Boston area fingered the Somerville Theatre as the location about a week before the big event. Unfortunately for Tauro, those same rumors named him as one of the show’s organizers, resulting in more than a few e-mails begging him for tickets.

Tauro claims Carreiro stalked him for three days, called him several times and threatened to make Tauro’s personal banking information public. Tauro also claims Carreiro even posed as a private detective.

But there are two sides to every story, and Carreiro’s side claims, although he knew Tauro from childhood, he did not approach the businessman for U2 tickets.

Saying Tauro’s allegations are “unfounded,” Carreiro’s attorney, Will Korman, told the Herald his client has “no involvement with the criminal justice system whatsoever” and he is “absolutely embarrassed, mortified and shell-shocked that this is happening to him.”

Tauro’s attorney, Anne Vigorito, provided a few choice quotes of her own, describing how rumors falsely identifying her client as having a connection to the secret gig resulted in him being deluged with ticket requests.

“You would have thought it was the Second Coming,” Vigorito said. “He had no access to tickets, but people believe what they want. Would they do this for the Jonas Brothers?”

Ironically, according to Vigorito, although her client isn’t that big a U2 fan, he did snag a press pass for the event.

“Billy’s more of a Frank Sinatra guy,” Vigorito said.
