Video lights fire at JPMorgan

NEW YORK (CNN) -- JPMorgan Chase & Co said it was reviewing its security procedures after a video posted online showed someone holding various documents found in trash cans containing customers' personal information.

The nation's third-largest bank became aware of of the video, posted by a union member on the popular Web site YouTube, on Tuesday, JPMorgan's (Charts, Fortune 500) spokesman Tom Kelly said. The union said the documents were found in the curbside trash of several banks.

"We are looking to see if this was an isolated situation and reinforce procedures," Kelly said.

The video, filmed by the local chapter of the Service Employees International Union (SEIU), was posted in response to the company's hiring of security contractors.

Last week, union members went through the curbside trash of several banks in Manhattan, Brooklyn and Queens, according to Linda Tran, an SEIU spokeswoman.

"Sometimes, to get people's attention, you need clear evidence that precipitates a conversation," Tran told CNN.

Kelly said the bank's customers are urged to check bank statements and monitor their accounts.

"We hope that the union people who got this personal info would not misuse it," he said.
