D.A. investigators spent more than six hours going over and collecting documents from the district offices of San Francisco City College on Gough Street.
The raid was part of an ongoing investigation into allegations that City College may have misused public funds back in 2005 while promoting a bond measure.
Voters approved measure a, giving City College $246 million to complete the second phase of its renovation and rebuilding project.
The D.A. is investigating whether a $10,000 rent payment that should have gone to the college was instead diverted to the bond campaign.
In another case, a $20,000 lease payment is said to have gone to the same campaign rather than to the college.
All the money was eventually returned to City College.
A source told ABC7 news City College officials have been cooperating with the D.A.'s office for more than two years and questioned Wednesday's action.
Investigators confiscated contracts made with vendors and copies of e-mails.
A spokesperson from D.A. Kamala Harris' office said there were not at liberty to discuss any aspect of the investigation.
City College did its own investigation and found that indeed the money was diverted. Then Chancellor Philip Day was partly to blame. Day is no longer chancellor. He is the president of the National Association of Student Financial Aid Administrators in Washington DC.
