When officers arrived at the home, they allege that Hamran became combative and ordered the officers off his property. Hamran picked up a stick and began threatening the officers.
Hamran was arrested and his roommate told police that he had a shotgun in his bedroom.
Police found the shotgun and Hamran then told officers that he had weapons in the garage as well.
The Orange County bomb squad was called in. They found 5 pipe bombs in a gun safe in the garage along with rifles, handguns and over a thousand rounds of ammunition.
Hamran is 36-years-old and lives at the house with a roommate.
He is now in police custody and will undergo a mental evaluation.
Police allege that he made some very serious threats not only against the police officers, but also against President Obama.
"The pipe bombs were found inside the safe with all this ammunition," said Lt. Alex Bastreri, Fullerton Police. "If something would've created or caused one of the pipe bombs to detonate, then all that ammunition could have detonated as well, which could have created an explosion. "With that much ammunition and 5 pipe bombs, regardless of the size, I believe they were about 4 inches in length, that could have created quite an explosion and cause a fire as well," said Lt. Basteri.
The pipe bombs were rendered safe at the home.
Hamran could face a number of charges, including possessing explosives. Police also allege that during the previous weekend, he discharged a firearm inside the Fullerton home so he could face charges for that as well.
