FULLERTON – Police officers seized nearly 1,000 pounds of illegal fireworks after a tipster notified them of the cache, officials said Friday.

Police responded to the 3500 block of West Avenue late Thursday and discovered the fireworks and arrested four people, Fullerton Sgt. Kathryn Hamel said.

Duane Duff, 45, was arrested on suspicion of felony possession of fireworks, while Lino Macias, 45, Anthony Reynoso, 49, and Robert Murphy, 45, were cited for misdemeanor possession of fireworks and released.

Duff was in jail with a $20,000 bail amount.

Police photos show the beds of two pickup trucks filled to the brim with the fireworks. Police said the suspects intended to sell the fireworks.

So-called safe and sane fireworks, which police say these were not, are legal in Fullerton; they can only be set off between 10 a.m. and 10 p.m. on the Fourth of July.
