Private Investigator in Los Angeles, California
Blue Systems International operates two Los Angeles private-investigator offices — one in Downtown LA at 740 1/2 San Pedro St (90014), open 24 hours, and one in Mid-Wilshire / Koreatown-adjacent at 544 N Western Ave Unit F (90004).
We are licensed under California Private Investigator License No. 28286, insured, and bonded. Our DTLA office answers at (800) 901-1360 around the clock; Mid-Wilshire at (310) 307-3738.
LA is unique in the market we cover. It's the biggest metro in California, which means our LA caseload skews toward attorney-retained work (civil discovery, deposition prep, asset searches ahead of litigation), high-net-worth family-law investigations (hidden-asset divorces, custody surveillance across neighborhoods from Beverly Hills to Pasadena), corporate internal investigations (trade-secret theft, insider leaks, employee fraud), and cyber-enabled fraud (BEC schemes, pig butchering, crypto-fraud with blockchain tracing).
Call (800) 901-1360 for a free, confidential consultation. We quote flat-rate for every engagement — never hourly surprises — and respond to LA inquiries same-business-day.

Why LA Clients Choose BSI
Direct access to the investigator — you work with the person running your case from intake through delivery, not a scheduler or case manager.
Flat-rate pricing, every time — written quote at intake, nothing above what you agreed to at retainer. No hourly surprises. No scope creep.
Evidence Code admissibility — every report we deliver is prepared to California Evidence Code foundation + authentication standards. The moment a case moves to deposition or trial, nothing we produced gets excluded on a technical objection.
Full LA coverage — DTLA office is 24/7 for urgent matters (missing persons, time-sensitive surveillance). Mid-Wilshire office covers Koreatown, Hollywood, Hancock Park, Larchmont, Mid-City. Field operations extend to Westside, SFV, Pasadena, South Bay, and Long Beach.
Confidentiality + discretion — we handle high-visibility clients, celebrity-adjacent cases, and executive-level corporate matters. Our DTLA + Mid-Wilshire locations are discreet entry points.
Call (800) 901-1360 for a 24-hour DTLA line, or (310) 307-3738 for the Mid-Wilshire office.
