Carroll was in Fayetteville visiting friends when the incident occurred. Carroll played for the University of Arkansas before he was selected in the first round of the 2004 NFL Draft by the Green Bay Packers.
Carroll's attorney, Sam Hilburn, said his client was charged with resisting arrest, assaulting a police officer and disorderly conduct, all misdemeanors. Carroll was kept in a holding cell for 15-20 minutes before being released on a $1,500 bond.
Hilburn said the disagreement began at a piano bar when a bouncer wouldn't let Carroll and his friends in.
"They said it was full, but it wasn't full," Hilburn said. "One of the guys got into a disagreement with the bouncer and punches were thrown, but Ahmad had nothing to do with that. Ahmad just walked away."
After the incident, Hilburn said Carroll and his friends went to another bar where they were confronted by police.
"After Ahmad said he didn't know anything about what happened at the other bar, one of the cops told him he was free to go, and when Ahmad tried to walk out of the bar, the other cop wouldn't let him go," Hilburn said. "He grabbed Ahmad's arm. Ahmad jerked his arm away and then the cop pulled a taser out before he arrested him."
Hilburn said he's already talked to three witnesses who said that while some of the people in Carroll's party had been drinking, that Carroll said he had not had anything to drink.
Hilburn said he didn't thing anything serious would happen as a result of the arrest.
"It's not serious. He didn't do anything," Hilburn said. "After they released him, he was signing autographs for the other policemen before he left."
Earlier this month, Packers middle linebacker Nick Barnett was kicked out of a Milwaukee nightclub after allegedly attacking the venue's emcee. No charges were filed, though, the emcee said he plans to file a complaint.
