A Calgary pastor is facing charges for a hate-motivated crime after an incident at the Seton Library.

On Feb. 25, a "Reading With Royalty" event was planned at the library, where drag performers were scheduled to read books about inclusion to families in attendance.

These events have been the subject of protests in the last few years, as was the case here, with multiple "aggressive" demonstrators turning up to the event.

According to the Calgary Police Service (CPS), several individuals entered the classroom where the event was happening at the library and hurled homophobic and transphobic slurs at the event's hosts and attendees, which included parents at children.

They refused to leave and police were called, and library staff were assisted by a pair of attendees in removing the individuals from the room while officers were on the way.

Officers removed the protesters from the facility on arrival and remained on scene afterwards.

One man was arrested; 36-year-old Derek Scott Reimer.

He's been charged with one count of causing a disturbance and one count of mischief.

Additionally, City of Calgary peace officers charged Reimer with six counts of harassment under the Public Behaviour Bylaw.
