CBS4 has learned that Denver police issued an arrest warrant Thursday for Denver Broncos strong safety T.J. Ward, a prized free agent pickup.

According to documents reviewed by CBS4, Ward is wanted in connection with an incident that took place May 9 which is categorized both as an assault and disturbing the peace.

The warrant became active Thursday. It was issued for Terrell R. Ward, T.J. Ward’s real name. The date of birth on the warrant matches Ward’s date of birth.

Court records reveal little about what prompted the issuance of the arrest warrant. However, sources say the warrant was issued in connection with a scuffle at a Denver nightclub.

The Broncos agreed to terms earlier this year with Ward, who previously played for the Cleveland Browns and was a Pro Bowl player.
