Tsungyu Chien, also known as Arnold Chien, was arrested on October 21, 2025, by the Arcadia Police Department on charges related to the sexual abuse of a minor.
The Report and Investigation
The Arcadia Police Department arrested Chien following an investigation into allegations of sexual abuse. On November 3, 2025, the Los Angeles County District Attorney’s Office formally filed three charges against him.
Chien worked as a tutor in the Arcadia area, giving him regular access to minors in private, one-on-one educational settings. Due to his work as a tutor and his extensive contact with children, authorities believe there may be additional victims.
The Criminal Charges
Chien faces serious charges:
Police Seeking Additional Victims
The Arcadia Police Department has made a public appeal asking anyone who may have had inappropriate contact or interactions with Chien to come forward. This public request strongly indicates investigators believe additional children may have been victimized.

When a tutor sexually abuses students, both the individual perpetrator and any tutoring companies or agencies can be held accountable through civil lawsuits.
Can You Sue Tutoring Companies or Agencies?
Yes. If Chien worked through a tutoring company, agency, or educational service, they may be liable if they:
Negligently Hired the Tutor:
Negligently Supervised:
Knew or Should Have Known:
Failed to Protect Students:
A Los Angeles child abuse attorney can investigate whether any tutoring companies, agencies, or educational institutions failed in their duty to protect students.
Tutors occupy positions of tremendous trust and authority, making them particularly dangerous when they abuse that power.
The Power Dynamic
Grooming Tactics Tutors Use
Sexual predators who work as tutors often follow similar patterns:
Victims of tutor sexual abuse may recover substantial compensation through civil lawsuits.
Economic Damages
Non-Economic Damages
California does not cap non-economic damages in sexual abuse cases, allowing juries to award amounts that truly reflect the harm.
Punitive Damages
When tutoring companies or agencies act with conscious disregard for student safety:
Recent California tutor and educator sexual abuse settlements range from hundreds of thousands to over $10 million depending on case specifics.
AB 218: Extended Time to File | AB 452: Elimination of SOL
California’s AB 218 and AB 452 laws provide significant protections for victims of sexual abuse:
Filing Deadlines:
No Criminal Conviction Required: You can sue even if criminal charges don’t result in conviction
Lower Burden of Proof: Civil cases require “more likely than not” instead of “beyond reasonable doubt”
Both Tutor AND Companies Can Be Sued: Hold all responsible parties accountable

No Fees Unless We Win
Q: Can I sue even if I don’t know which tutoring company Chien worked for?
A: Yes. Our investigators will determine all entities Chien worked with or through. We handle the investigation.
Q: My child only had a few tutoring sessions with Chien. Can we still have a case?
A: Possibly. Even brief contact can result in abuse. Consult an attorney to evaluate your specific situation.
Q: How long do I have to file a lawsuit?
A: Under AB 218, victims can file until age 40 or within 5 years of discovering psychological injury. However, acting sooner preserves evidence. Call (866) GO-SEE-SAM to discuss deadlines.
Q: Will my child’s identity be public?
A: No. All child sexual abuse cases use pseudonyms (Jane Doe/John Doe) to protect victims’ identities.
Q: How much does a Los Angeles child abuse lawyer cost?
A: Dordulian Law Group works on contingency – you pay nothing unless we win.
Q: What if the criminal case doesn’t result in conviction?
A: Civil cases are separate and have a lower burden of proof. Many civil cases succeed even when criminal prosecution doesn’t.
Q: What if my child is now an adult but was abused as a minor?
A: California’s extended statute of limitations allows victims to file until age 40. Adult survivors have legal options.
