Hateful messages painted on Arlington's Martin High

Arlington police hope surveillance video will help track down the people who spray painted hate speech around Martin High School.

Workers quickly painted over the racist and anti-transgender messages, but not before students posted pictures of them online.

One read “trans only” on a locker room door. The other read “whites only” near a water fountain.

Detectives believe the offenders may be from Arlington High, a rival school. They could be charged with a felony offense.
