NBA great Scottie Pippen is being sued by an autograph-seeker for an altercation that happened outside a Southern California restaurant.

Via CBS News, attorneys for the autograph-seeker filed a lawsuit for $4 million Thursday in Los Angeles. They claim their client, Camran Shafighi, asked Pippen for an autograph for his girlfriend's son and suffered a "brutal and unjustified" attack.

According to officials in the sheriff's department, Pippen was eating with his family June 23 in Malibu at an upper-scale sushi restaurant. They say Shafighi was taking pictures and requesting autographs both inside the restaurant and then again in the parking lot, when an argument turned violent, which ended with Shafighi being treated at a hospital for a head injury.

After the incident, Pippen was questioned but not arrested or charged.

Pippen, 47, played 17 seasons in the NBA, winning six championships as a member of the Bulls alongside Michael Jordan. Pippen was named one of the 50 greatest players by the NBA.

Pippen was hired in October 2012 to serve as an advisor to Bulls president and COO Michael Reinsdorf.
