The fans of the Oakland Raiders have long been associated with rowdy, and sometimes violent, behavior, but a review of recent police records reveals that 49ers fans currently hold the Bay Area title for breaking the law on game day.

NBC Bay Area looked at the police logs tied to NFL games at the Oakland Coliseum and Levi's Stadium so far this year, and found that there are nearly twice as many arrests per game among the 49ers faithful compared to Raiders fans.

This past Sunday, Santa Clara police officers arrested 22 people at Levi's stadium, and while the vast majority were for non-violent incidents involving alcohol, two people were taken into custody after a bloody fight in a stadium bathroom.

The number of arrests at Sunday's game was actually lower than the per game average at Levi's stadium this year of 25.2 arrests.

Meanwhile across the bay at the Coliseum, Raiders fans have averaged 12.3 arrests per game, according to data from the Oakland Police Department and Alameda County Sheriff's Office.

It is important to note, however, that there has been only one regular season game at the Oakland Coliseum – in addition to two preseason games. The Alameda County Sheriff's Office says there are generally more arrests during regular season games. And the data from the Coliseum for 2014 supports this.

For the two preseason Raiders games, there were a combined total of 16 arrests. But during the Raiders first regular season game, 21 fans were arrested.

However, this doesn't seem to be the case for 49ers fans at Levi's Stadium – arrests have been consistently high since the 49ers kicked off their new era at Levi's Stadium on Aug. 17 with a preseason game against Denver.

Below is the raw arrest data for both teams:

Levi’s Stadium Data:

Aug. 17 = 18 arrests

Aug. 24 = 38 arrests

Sept: 14 = 31 arrests

Sept. 18 = 17 arrests

Oct. 5 = 22 arrests

O.Co Coliseum Data:
