MINNEAPOLIS -- Election officials called off a Minneapolis caucus after a fight broke out Tuesday night at the Brian Coyle Community Center in Minneapolis.

According to MPR News, a crowd was riled up at the community center, where supporters of Minneapolis School Board member Mohamud Noor were hoping to outnumber backers of DFL state Rep. Phyllis Kahn, who has held her seat for more than 40 years.

"There was some sort of altercation," says MPR reporter Mat Sepic. "The police escorted the people who were fighting out of the building and party officials shut down the caucus."

Sepic says the disagreement was over leadership of the caucus and didn't have directly to do with the differences between Kahn and Noor.

Police, who were on site before the caucus began, were called back to help calm the crowd. No arrests were made.
