suspicious fire

Intentionally set flames

A suspicious fire is one that appears to have been set deliberately rather than starting by accident or natural causes.

The phrase is used by investigators, journalists, and insurance companies when arson is suspected but not yet proven: Police are treating the warehouse blaze as a suspicious fire.

It implies an ongoing investigation.
