Excerpts from the dailyherald.com:

Barrington firefighters responded to a fire Tuesday morning at a three-unit apartment building in the 300 block of East Russell Street. One person was treated and released at the scene.

A resident called the fire department at 7:49 a.m. after seeing smoke coming from the first floor where a sauna was located. When firefighters arrived, they found heavy smoke and fire and did not immediately know whether other residents were home. They brought the fire under control within 27 minutes.

One unit sustained heavy fire damage while the other two units had smoke damage. The entire building was declared uninhabitable and residents are being assisted by the Red Cross with relocation and other immediate needs. The cause of the fire remains under investigation but is not being considered suspicious.

Assisting Barrington were firefighters from the Barrington Countryside FPD, Lake Zurich, Fox River Grove, Long Grove, Buffalo Grove, and Wauconda.
