Dream, whose birth name is Terrius Nash, was booked on two felony counts of assault and strangulation, in addition to misdemeanor assault, reckless endangerment and child endangerment.
The 36-year-old father of five was originally wanted by the NYPD for questioning and is reportedly still in custody.
Nam claims Dream kicked, punched and choked her during an argument at the Plaza Hotel in New York last April. The incident wasn't reported until seven months later. Another domestic altercation occurred in June 2013, in Newport Beach, Calif. The local D.A. dropped the case because Nam declined to press charges.
According to TMZ, Dream denies attacking his ex, and believes the Canadian-born Nam is using the assault story as a way to extend her U.S. visa.
