People stealing metal, computers and other equipment have done more than a million dollars worth of damage to Flint school buildings in the past 18 months.
Linda Thompson is the Flint Community Schools superintendent. She says the problem goes well beyond kids with spray paint.
Thompson says in one case a school building was ransacked as part a sophisticated scheme.
"These are not kids doing this," Thompson insists, "You can look at the fact that electricity was disconnected….we’re talking about people who are not amateurs about doing this either."
Thompson is worried vandals might take advantage of the upcoming Christmas break to do more damage to Flint schools.
She’s urging people to report any suspicious activity around Flint schools to the police.
Thompson says Flint is not alone. Many urban school districts have seen a big increase in vandalism during the past few years.
