Police presence at Royal Alexandra Hospital after lockdown

The Royal Alexandra Hospital was locked down briefly on Thursday after threats of violence.
Edmonton police say hospital workers received a phone call in the late afternoon from a person who became aggressive and threatened gun violence.
The call prompted hospital administration to lock down the building and call police.
The lockdown was lifted around 6 p.m. after it was decided there was no threat to public safety, the hospital said. However, EPS officers remained on site into the evening.
