An 18-year-old man in Thompson, Man., has been arrested after threats were made at a local high school.

RCMP say the man was arrested earlier this week in connection with the threats, which were allegedly made at R.D. Parker Collegiate.

The threats allegedly stated that the school and City Centre Mall in Thompson were to be the targets of violent acts on Thursday, according to police.

The man, a former student of the school, was arrested in Winnipeg on Monday and remains in custody.

He has been charged with two counts of uttering threats and one count of failing to comply with an undertaking, police said Thursday. His name was not released.

RCMP Sgt. Line Karpish said no one wants to see a repeat of the mass shooting on Dec. 14 that killed 26 people — including 20 children — at Sandy Hook Elementary School in Newtown, Conn.

"We are now living in an environment where making statements that certainly allude to jeopardizing the safety and the security of the Canadian public — whether it be in our schools or in our airport — is taken very seriously," Karpish said.

"Things that may have been construed, you know, as funny 15 [or] 20 years ago are no longer funny anymore," she added.

In a separate incident earlier this week, another teenager was charged after threats were allegedly made at a school in St. Norbert.
