A 38-year-old woman is in police custody in Saskatoon following a bizarre pair of assaults involving an elderly woman and a police officer.

Saskatoon police say an 84-year-old woman was walking on 4th Avenue North at around 4:45 p.m. CST Sunday when the suspect approached her, pushed her to the ground and kicked her.

Police added that while the suspect was being detained and booked, she started kicking a male officer.
