Talib and his brother, Yaqub, had been under investigation over an alleged aggravated assault at a downtown Dallas nightclub on April 8.
Police had released a statement with details of the incident but did not identify the parties involved.
On Friday, Dallas PD released a statement saying the case has been suspended "pending further leads."
"Dallas Police Assault Detectives have been investigating an alleged offense that occurred in the early morning of April 8, 2015," the statement reads, according to The Dallas Morning News. "This incident occurred outside a club at the 700 block of North Pearl. Detectives interviewed the Complainant, contacted witnesses and gathered evidence. Based on these interviews and the evidence currently available, this case has been suspended pending further leads."
Talib has been named to the Pro Bowl in each of the last two seasons. The 29-year-old was drafted by the Tampa Bay Buccaneers in the first round in 2008, where he played five years before being traded to the New England Patriots.
In 2009, Talib was suspended one game by the NFL after being arrested for simple battery and resisting arrest for assaulting a cab driver. In 2011, he and his mother were charged with aggravated assault with a deadly weapon after an altercation with the boyfriend of his sister. The charge was later dropped after his attorney said prosecutors did not believe their chief witness was credible.
Talib signed a six-year, $57 million contract with the Broncos in March 2014. Last season, he recorded 67 tackles and four interceptions for Denver.
