Police responded Thursday afternoon, following an outburst by Councilman Tom Berg during a public hearing.

It's not the first time Berg's clashes with colleagues has escalated into a 911 call.

The people in the room say they were uncomfortable or even afraid.

Members of the Transportation Committee wanted an update from the city on the effort to condemn land and relocate families in the path of rail.

Committee Chairman Breene Harimoto acknowledged that confidential information couldn't be shared.

"I think the situation was serious.  I wasn't sure what was going to happen next," said Councilman Stanley Chang, who was in the room.

"I don't know who called the police and I don't know why.  I felt I was exercising due diligence under the agenda," said Berg. 

This is not the first time Berg has had confrontations in public settings.

Last November, during the Asia Pacific Economic Cooperation conference, police say Berg tried to reenter an event without proper credentials and appeared drunk. 

Police also responded to a Waipahu neighborhood board meeting last year after Berg insisted on speaking in front of the group.

Harimoto did not want to appear on camera but told KITV4 News, "I can tell you I was afraid.  I couldn't contain him. He was totally out of control."
