A day after The Washington Post reported his attempted murder warrant, ex-Steeler Antonio Brown posted a cryptic photo on social media.

Former Pittsburgh Steelers wide receiver Antonio Brown is wanted in Miami-Dade County, Florida on an attempted murder charge, according to a court document obtained by the Washington Post. The documents state Brown was allegedly involved in a shooting at Adin Ross’ celebrity boxing event in May.

The arrest warrant shows a charge of attempted second-degree murder after Brown was accused of firing a gun at a boxing event in Florida.
