DALLAS (CBSDFW.COM) – At about 6 p.m. Wednesday, the Dallas Police Department sent the media a news release with a strange request: Check Facebook.

Sure enough, on the department’s Fan Page, spokesman Warren Mitchell – he was the one who sent the check-Facebook-release, at least – announced the second arrest in the Memorial Day weekend tagging of Central Expressway.

At about 5 p.m. on May 29, a group of more than 75 motorcycle riders blocked all the northbound lanes at Central Expressway and Mockingbird Lane to pull tricks and spray graffiti on the freeway honoring a friend who died in an accident in 2009, according to a YouTube video uploaded shortly after.

The same thing happened in 2010.

Thomas Michael Roberts, 35, was arrested on June 10 and charged with felony graffiti, which carries a jail sentence between 180 days and two years prison and a fine of up to $10,000.

In Wednesday’s Facebook release, police announced Kenneth Ray Hernandez, 27, was arrested in Grapevine and booked on identical charges.

“Social media and tips continue to play an important part in this ongoing investigation,” reads the Facebook release.

Shortly after the 2011 tagging, the department took to Facebook, explaining the crime and asking for the public’s help.

“The Dallas Police Department will utilize social media resources to track, identify and prevent future acts of this nature,” read the June 6 release posted on the social media site. is awaiting comment from the department. The release also notes the investigation is ongoing.
