A 31-year-old Riverside massage parlor worker accused of sexually assaulting a woman could have targeted others, prompting police Thursday to ask anyone aware of any past incidents to come forward.
Pantanan Gunkhunthod is charged with forcible sexual penetration and sexual battery for the alleged attack, which occurred in May.
Gunkhunthod pleaded not guilty during an arraignment Tuesday before Riverside County Superior Court Judge Charles Koosed, who scheduled a bail-setting conference for Wednesday at the Riverside Hall of Justice.
The defendant, who has no documented prior felony convictions, is being held on $50,000 bail at the Robert Presley Jail in Riverside.
According to Riverside police spokesman Officer Ryan Railsback, Gunkhunthod was a staff masseur at Serenity Thai Massage in the 3700 block of Nelson Street.
During a full-body massage on May 21, he allegedly assaulted the woman, whose identity was not disclosed. Railsback said the victim reported the alleged attack to detectives from the police department’s Sexual Assault-Child Abuse Unit soon afterward, leading to a months-long investigation that culminated in the defendant’s arrest on Oct. 27 at his residence on Magnolia Avenue.
“During their investigation, detectives learned an anonymous complaint was made to the city’s 311 Call Center a couple months prior against this same business for a similarly described incident,” Railsback said. “Detectives did look into this complaint but could not sustain the allegation based on limited information provided at the time. Consequently, detectives believe there may be additional victims who have not yet come forward.”
Anyone with information was asked to contact SACA investigators at 951-353-7950.
