So far, one person has been arrested on suspicion of attempted felony vandalism. Police said Jeremiah Kean Mayman, 31, of Venice was booked Thursday night after he allegedly tossed 1½-inch nails onto flight school property as he rode past on a bicycle.
Mayman has been released on bail, which was set at $20,000. Authorities are trying to determine whether he is connected to six other incidents between late March and mid-May in which hundreds of roofing nails were strewn in the driveways of Justice Aviation, Krueger Aviation and American Flyers.
