A hazmat crew was called to a Northwest D.C. home Monday afternoon after the new homeowners discovered a suspicious substance in an old safe.

Authorities arrived at the home at 3736 Kanawah St. NW around 4 p.m.

D.C. Fire & EMS, assisted by an Army explosives team, removed several vials of powder and liquids from the home. The items were taken to a lab for testing.

Authorities said the home had recently been sold. The new owner called 911 after discovering the contents of a 40-year-old safe that had been left behind in the basement.

The homeowner said he found containers with a white, syrupy substance in the safe.

There were no evacuations and no injuries.

Authorities remained on the scene until about midnight.
