The 24-year-old Liggins was arrested Saturday after his girlfriend told police he attacked her in front of their 2-year-old son.
The Oklahoman reported Friday that Liggins was charged with three counts of domestic abuse, two counts of domestic assault and battery with a dangerous weapon, one count of kidnapping and one count of violating a protective order.
The newspaper said 23-year-old Marcus A. Rogers was charged as a co-defendant with Liggins on one count of kidnapping, and also is charged with an additional count of kidnapping and one count of assault and battery.
Liggins and Rogers are free on bail.
Liggins appeared in 39 games for the Thunder last season, averaging 1.5 points, 1.4 rebounds and 7.4 minutes. In 56 career games with Orlando and Oklahoma City, the former Kentucky player has averaged 1.6 points and 1.2 rebounds.
