Roads were closed off in downtown Hamilton Friday afternoon when a suspicious package was left near the Central Police Station.

Emergency crews shut down an area on Rebecca Street between Ferguson Avenue North and Mary Street for the investigation. Those roads have since been reopened.

Const. Steve Welton told CBC News that the package contained a "powdered substance." The Emergency Response Unit has seized the package and police now say there is no immediate danger to the public.

A daycare and a senior's home in the area were placed in a hold and secure while the investigation was conducted.

Police are now trying to determine if there are grounds to launch a criminal investigation, Welton said.
