Calgary police have charged the former president of Mount Royal University's Student Association with robbery after a heist at a southeast bank on Wednesday.

Meghan Darcy Melnyk has been charged with robbery, possession of a prohibited weapon, and committing an indictable offence while disguised.

Outstanding warrants for Melnyk were also executed at the time of her arrest for fraud, uttering forged documents, and a breach of probation.

Melnyk served as president of Mount Royal's Student Association this year but, according to reports, she resigned from the position last month. 

At about 1:40 p.m., a woman entered the Servus Credit Union in the 5300 block of 68 Ave. S.E. and approached the teller.

She handed over a note saying she had a weapon and demanded cash.

She then left the bank with an undisclosed amount of money.

With the assistance of HAWC2, the suspect's vehicle was tracked and she was subsequently arrested by members of the tactical team.
