The investigation is the latest episode in a series of embarrassing incidents for San Fernando's local government.
A YouTube video in the middle of the controversy shows a San Fernando police officer writing a ticket to Fred Anthony Flores, who is a high-ranking aide to Rep. Howard Berman.
Flores appears agitated in the video, but he told the San Fernando Valley Sun that was not the case. The video appears to come from the patrol car's dashboard camera, indicating that someone from the police department could have played a role in posting it on the Internet.
On Jan. 19, Lt. Jeff Eley was placed on paid leave after accusations surfaced that he fixed that ticket for Flores. The Los Angeles County Sheriff's Department is investigating that case.
Eley is the acting chief in place of Tony Ruelas, who is under investigation for having an affair with a police cadet.
All of this comes on the heels of a scandal involving the mayor. In December 2011 during a council meeting, Mayor Mario Hernandez told city officials and residents that he was having an affair with Councilmember Maribel De La Torre - all while the mayor's wife was sitting in the front row.
Many residents are fed up with all of these scandals. A number of recall petitions have been started to get rid of the mayor and several council members.
The city's police department has not commented on the issue.
