A 17-year-old American from Oregon is facing charges of attempted murder for planning to stage a bomb attack in his school, the West Albany High School.

Based on a tip placed at 911, law enforcement officers from the Albany Police Department stormed the house of Grant Alan Acord on Thursday and found six home-made bombs. The bombs were discovered hidden in Mr Acord's bedroom. He will be charged as an adult.

Mr Acord will be slapped one count of aggravated attempted murder, as well as six counts each of manufacturing a destructive device, possession of a destructive device and possession of a weapon with intent to use it against another person.

Apart from the destructive devices, plan, checklists and a diagram of West Albany High School were also discovered in his bedroom. One of the documents even had a date written on it as to when the West Albany High School student plant to detonate his bombs.

Investigators, upon more detailed scrutiny, found Mr Acord's plan was to launch a terror threat incident "specifically modeled after Columbine."

A school shooting that occurred on April 20, 1999, Eric Harris and Dylan Klebold, senior students at the Columbine High School staged a massacre that killed a total of 12 students and one teacher. The two youth staged a complex and highly planned attack that involved a fire bomb to divert firefighters, propane tanks converted to bombs placed in the cafeteria, 99 explosive devices, as well as bombs rigged in cars.

Although the motives of the pair, who committed suicide, remain unclear, their action has been described by the USA Today as "a suicidal attack (which was) planned as a grand - if badly implemented - terrorist bombing."

Mr Acord's motive, to date, has likewise yet to be identified, according to Benton County District Attorney John Haroldson.

Among the explosives found in his bedroom included pipe bombs, Molotov cocktails, napalm bombs as well as those made from drain cleaner.

The young lad is scheduled to appear in court on Tuesday.

"This went above and beyond teenage curiosity," Albany police Capt Eric Carter had earlier told Portland's KATU-TV. "This is beyond a kid playing with a couple of cherry bombs. It was serious enough to warrant calling out the bomb squad."
