Thornton, Pennsylvania, April 2 (CNA) A Taiwanese student who was arrested in the United States last week for threatening to shoot up his school had built a 9mm handgun with parts bought online and had over 1,600 rounds of ammunition for various firearms, U.S. media reported Monday.

An Tso Sun (孫安佐), 18, had approximately 225 rounds of 12-gauge ammo, 663 rounds of 9mm ammunition, 295 rounds of AR-15 ammunition, and 425 rounds of AK-47 ammo, cbsphilly.com said, citing Michael Chitwood, superintendent of the Upper Darby police in Pennsylvania.

Upper Darby police had previously revealed that Sun’s school-issued iPad showed searches on how to buy an AK-47 or an AR-15 semi-automatic rifle.

The student at Monsignor Bonner Archbishop Prendergast Catholic High School allegedly was planning an attack on May 1. He was arrested and detained on March 27 on charges of making terrorist threats.

The Archdiocese confirmed to CBS3 that Sun has since been expelled, the report said.

“In my opinion, based on the totality of everything, we certainly feel he was going to shoot down the school,” Chitwood was quoted as saying in a news conference Monday.

The teenager’s parents, actor Sun Peng (孫鵬) and opera singer Di Ying (狄鶯), have maintained that he was joking when he talked about shooting up his school.

The couple, who arrived in the United States on March 30, visited their son at Delaware County Prison on Monday morning accompanied by lawyer Robert Keller, whom they have retained to represent their son.

Keller later told the media that the parents were very emotional and cried during what he described as a “heartwarming” meeting.

Sun Peng and Di Ying love their son very much and will do their utmost to protect him and ensure that he obtains the best defense possible, according to Keller.

A hearing on the case is scheduled for April 11, he said, adding that it is still premature to discuss how the case will develop.
