El Monte police say they've seized two tons of illegal fireworks.
Detective Ralph Batres says the seizure was made Monday night in downtown Los Angeles as part of an ongoing investigation.
The fireworks were worth an estimated $125,000.
No arrests have been made.
Authorities are on the lookout for illegal fireworks in Southern California as the July 4th holiday approaches.
Last week, Los Angeles County sheriff's deputies say they seized a half-million dollars worth of fireworks in La Puente and arrested two men.
