An encampment fire caused a massive plume of smoke to rise above downtown Seattle Monday afternoon.

The fire sparked in an encampment at Mercer Street near Fairview, close to an Interstate 5 onramp. Eastbound lanes of Mercer Street were blocked while firefighters worked on the scene.

There were no injuries reported and firefighters did not find anyone in the encampment.

Seattle Fire Department investigators say the fire on Mercer Street was intentionally set. A 46-year-old man was arrested for investigation of reckless burning.

The smoke plume from the fire could be seen from across the water on Alki Beach.
