Buffalo police and firefighters said a "suspicious package" containing white powder was mailed to the law offices of Cellino and Barnes in Main Place Tower today.
Deputy Fire Commissioner Johnathan Eaton said it was not believed to be a harmful substance but the 25th floor was quarantined during the investigation as a precaution. The rest of the building remained open.
According to a source familiar with the investigation, a man and a woman opened the package, which was delivered by U.S. Postal Service, and white powder flew out. There was a threatening note inside the envelope. The two were evaluated by paramedics at the scene and were taken to an area hospital as a precaution.
"Obviously, it's disturbing. People were rattled," said a person who was in the offices.
Neither Ross M. Cellino Jr. nor Stephen E. Barnes, who have been battling each other for over six months over Cellino's desire to leave the firm, were in the offices when the package was opened.
The Buffalo Fire Department's hazmat team, as well as police responded.
"I'm advised by the FBI not to comment, but I am going to say we're appreciative of the quick response from Buffalo police and firefighters," said Robert J. Schreck, managing attorney for Cellino and Barnes.
