Authorities say at least 34 people were injured after elevated carbon monoxide readings were detected Tuesday morning in the basement of 60 Murray Street, a commercial building in the Tribeca section of Manhattan.

Only one person is believed to have a serious injury and was taken to New York Downtown Hospital.

An oil burner fire may have sparked the high carbon monoxide readings.

The FDNY responded to a defective oil burner in the basement at 8:28 a.m.
