A star basketball player from Norcross High School was released on bond early Saturday after being arrested a day earlier on charges of aggravated assault and trespassing, police said.

Al-Farouq Aminu, a 6-foot-8 high school All-American who has signed to play basketball for Wake Forest, was arrested by Gwinnett County sheriff's deputies, police spokesman David Schiralli said.

He was released from the Gwinnett County jail at 1:18 a.m. Saturday after posting a $3,500 signature bond, according to the jail's Web site. The aggravated assault charge is a felony; trespassing is a misdemeanor.

Wake Forest coach Dino Gaudio said the school would not comment on the charges, saying in a prepared statement Saturday to the Journal-Constitution, "We are in the process of gathering all of the information on this incident and it would not be fair to make any statement or judgment until we collect all of the facts."

Aminu, a 17-year-old senior, turned himself in Friday after authorities obtained warrants for his arrest and was booked into the jail shortly before 6 p.m., sheriff's spokeswoman Stacey Bourbonnais said.

Aminu is accused of shooting a female with a BB gun from a vehicle on March 14, Bourbonnais said.

Bourbonnais said she did not know the extent of the victim's injuries and had no other details about the incident.

Gwinnett County Police Department spokeswoman Corp. Illana Spellman refused to provide any details of the arrest Saturday, saying she does not work on weekends if it involves only a "routine" arrest.

Friday, before news of Aminu's arrest became public, he was named Mr. Basketball by the AJC, an honor recognizing the state's best high school player. The AJC will do further reporting to determine whether Aminu will keep the designation, according to Ronnie Ramos, senior editor for sports and features.

One of his teammates, upon learning of the arrest, said Aminu is not a troublemaker.

"He is not that type of kid. I can't see Al-Farouq like that," said Norcross' starting point guard, Taariq Muhammad. "He was probably in the wrong place at the wrong time. This could serve as a lesson for other kids."

Aminu has developed into one of the nation's top players. Entering his senior season, he was named the No. 11 prospect by Rivals.com and No. 8 by Scout.com. One Web site, nbadraft.net, projects him as the No. 2 pick in the 2009 NBA draft should he opt to leave Wake Forest for a professional career after one season.

This year, Aminu led his team to a third consecutive state title, averaging 23.1 points.
