Former Raiders center Barret Robbins was released Tuesday from a Florida prison, where he had spent the past year and a half for a drug-related probation violation.

Robbins, who disappeared from the Raiders two days before the Super Bowl in 2003, was placed on probation in 2005 and ordered to continue treatment for bipolar disorder under a plea agreement resulting from a brawl with Miami Beach police.

CBS4 in Miami tried to interview Robbins on Tuesday shortly after he got out of Dade Correctional Institute, a state run prison in Florida City. The station said Robbins appeared unapologetic for his 2005 attack on three Miami Beach police officers.

Interviewer Gary Nelson asked Robbins if he could overcome alcohol and drug problems that have plagued him.

"I'm not worried about that, and that's not anybody's business but mine," Robbins replied. "That's something I'll deal with myself."

Robbins then broke off the interview and uttered an obscenity when asked if he owed the police officers an apology.

"You know what, cancel this, erase this. Erase what you got, I don't want any part of this," Robbins said, walking away from the camera.

Robbins was originally charged with three counts of attempted murder after attacking the officers at an Irish pub in Miami, according to CBS4 Miami.

Nelson said police shot Robbins twice, including once through the heart.

"I just started firing the gun," Miami Beach Detective Mike Muley, who was granting his first televised interview, told the station.

Robbins knocked away the officer's gun, then collapsed but survived the shot to the heart, the station said. He was sentenced to a stint in a treatment program and probation, said the Miami station, but was sent to prison for repeatedly violating his probation.

Robbins filed a lawsuit against police for use of excessive force. He described the incident as "just running into them and pushing them and getting shot," the station said on its website. The station said he lost the lawsuit.

The former Raider, who suddenly disappeared from the team the day before the 2003 Super Bowl, returned the night before the game but was left off the roster by coach Bill Callahan. Robbins said he had spent the day in Tijuana and hadn't taken medication for depression, which was diagnosed in college.

Robbins also was diagnosed with bipolar disorder following his disappearance before the Super Bowl, which the Raiders lost to Tampa Bay.
