SAN ANTONIO (AP) — Former NBA All-Star Alvin Robertson, facing sexual assault of a child and sex trafficking charges, is back in jail in San Antonio after a judge increased his bond.

Prosecutors say they had asked that Robertson's bail be doubled to $450,000 on Wednesday after allegations surfaced that he was threatening two women. The 47-year-old Robertson was still in jail late Wednesday.

He has been accused of being part of a sex trafficking ring that kidnapped a 14-year-old girl. Robertson, through his lawyer, has denied the allegations.

Attorney Jimmy Parks Jr. told the San Antonio Express-News the bond change was unusual because his client hasn't been charged with a new crime.
