TROY, Mich. -

With the start of a new school year just weeks away, the Troy Public School District is letting students know there will be a tough new policy against sexting when they come back to class.

The Troy School District Board of Education adopted a policy in early July that puts students on notice that cellphones, laptops and other electronic devices may be searched if there's "reasonable suspicion" of such sexually explicit communication.

District spokeswoman Kerry Birmingham said police could be contacted if such messages are found.

The American Civil Liberties Union of Michigan, however, has concerns about Troy's policy, including how broadly it defines materials of a sexual nature. The ACLU also is concerned that the searches may lead to police getting involved.
