There were several complaints by fans of the New Orleans Saints that they were spat upon, and that they encountered threats and intimidation.

Police Chief Greg Suhr said more officers will be at Candlestick Park this Sunday when the 49ers take on New York’s Giants in the NFC Championship game. The chief said security has been tightened after a “rough game” in August against the Raiders at the park where two fans were shot and another beaten.

KCBS’ Bob Melrose Reports:

“Even if you talk to some of the fans who’ve complained about how the language was on Saturday, [they] do concede the point that there was a far greater security presence,” he said. Suhr assured the SFPD have “a good plan in place.”

Suhr said people should not hesitate to call or send a text message to report unruly fans. Calls can be made to (415) 656-4949 or texts can be sent to 69050 with the keyword BADFAN, and will be kept confidential.
