DETROIT -

Overall crime was down last year on Detroit Public Schools campuses.

The district says Monday there were 120 fewer reported incidents in 2011-12 than the previous school year.

Just over 1,200 incidents were reported last year with 70 of 115 schools reporting declines in criminal activity.

Overall, burglaries and robberies were down by 28 percent, while felonious assaults dropped by 35 percent. Reports of concealed weapons dipped by 15 percent and arsons plummeted 61 percent.

Thirteen more criminal sexual conduct cases were reported.

The drop in crime appears to coincide with an increase in parental involvement.

The district says surveys show parent engagement last year was up by 30 percent. More than 4,800 parents also attended workshops and participated in fundraisers last year.
