PIPESTONE — A Pipestone Area Schools student has been arrested and suspended from school after bringing a BB gun to the middle and high school.

According to Pipestone County Sheriff Keith Vreeman, deputies arrested Bastian Alanzo Cole Erickson, 18, Monday morning at the school after a BB gun resembling a pistol was discovered in his possession. Although he was a student, Erickson's identity could be released because he's at least 18.

Erickson continued to be held at the Pipestone County Jail for disorderly conduct and threats of violence as of mid-Tuesday afternoon pending formal charges.

Vreeman said his office turned over its investigative materials to the Pipestone County Attorney's Office for a charging decision. He added that he expected charges to be filed soon, as the 48-hour window to have Erickson appear in court or file an extension closes at 10:30 a.m. Wednesday.

According to Vreeman, the sheriff's office responded to the report of a gun on school grounds at 10:15 a.m. Monday. Vreeman said another PAS student had reported Erickson to school officials, who already had him in an administrative office and was searching his backpack by the time law enforcement arrived.

PAS Superintendent Kevin Enerson noted that no threats were made and the school followed its policies and procedures.

The district issued a public statement within a couple hours of Monday's incident, alerting the public that the district was notified of a potential weapons policy violation. The district informed the public that a pellet gun had been discovered and that the student had been taken into custody. Classes reportedly continued as normal Monday.

Vreeman said he couldn't recall another incident in which a gun was reported at the school district during his career with the sheriff's office.

Vreeman said deputies couldn't have known it was a BB gun upon receiving the call, and responded as if it were a legitimate and dangerous weapon.
