Hartford police arrested a 29-year-old convicted felon Tuesday night in the weekend shooting of Alexander Bradley, a one-time associate of Aaron Hernandez, the former NFL star who is facing a murder charge, police said.

Leslie Randolph, of Hartford, is being held on $1 million bail on firearm and assault charges. He allegedly shot Bradley, 31, of East Hartford, Conn., three times in the leg outside a nightclub Sunday night in the South Meadows neighborhood of Hartford.

After being shot, Bradley allegedly retaliated by spraying the building with gunfire, sending people diving to the floor for cover. Police have said the fight began with a dispute with another person inside the club about money.

It was not immediately clear if Randolph had an attorney. The Associated Press reported that he has previous convictions for making threats, as well as drug and gun crimes, and has been in and out of jail over the past decade.

Hartford police searched for evidence Tuesday night at Randolph’s Southington home, where he was arrested; they also searched for evidence on Hillside Avenue in Hartford, according to the statement.

Bradley was ordered held Tuesday on $1 million bail in connection with the nightclub shooting, and is facing charges including reckless endangerment in the first degree, criminal possession of a pistol or revolver, stealing a firearm, and criminal use of a firearm. His attorney on Tuesday told reporters that his client should be considered a victim in the case.

Bradley has repeatedly made headlines in the saga involving Hernandez, 24, who has pleaded not guilty to murder and weapons charges in the June 2013 slaying of Odin Lloyd, 27, of Dorchester.

Bradley is suing Hernandez in federal court in Florida, alleging that the athlete shot him in the face there in February 2013.

In addition, authorities are investigating Hernandez’s possible involvement in a July 2012 double slaying in Boston’s South End, and the Globe has reported that Bradley was subpoenaed in October to appear before a grand jury that was hearing evidence in the case. He was arrested when he refused to testify.
