A racial slur appeared on a portable road sign along westbound I-94 in Detroit early today after the sign was hacked, officials said.
Motorists began calling police shortly before 1 a.m. to report the message, which was an apparent reference slain Florida teenager Trayvon Martin. The message, calling Trayvon a racial epithet, was on a sign near Michigan Avenue, MDOT spokesman Rob Morosi said.
Martin, 17, was shot to death in Sanford, Fla., on Feb. 26 by neighborhood watch volunteer George Zimmerman, who told police he acted in self-defense. A special prosecutor is now investigating the case.
The racial message was up for about an hour before it was changed back to the original message warning of upcoming road construction.
