Illinois, USA: Local media reports say US federal, state and local authorities are trying to determine what caused an overnight fire at a Sikh house of worship in Island Lake.

No one was hurt in the blaze at the Guru Nanak Sikh Mission of America, 217 W. State Road. The fire destroyed the building and destroyed the roof and some sections of the walls.

The fire was reported about 8:30 p.m. When crews arrived they saw flames in the building’s lower level, according to a news release from the Wauconda Fire Protection District.

Extinguishing the blaze was difficult because it was in the walls and floors, authorities said. It eventually was put out from outside the structure.

Crews from Lake Zurich, Fox Lake, Round Lake, Long Grove and other area departments assisted.

Investigators with the Federal Bureau of Alcohol, Tobacco, Firearms and Explosives were on the scene Wednesday (Nov. 12), as were officials from the state fire marshal’s office and local police and firefighters. They walked around the building, taking pictures and looking for clues.

A loss estimate was not immediately available.

The Gurdwara Saib was opened in 1997 in a building that was erected in 1943.
