    June 24 (Reuters) - An employee at an agriculture co-op was
killed on Monday by an explosion in a grain silo in rural
northwestern Indiana, local authorities said.
    The explosion occurred at about 1:30 p.m. CT (1830 GMT) at
the Co-Alliance fertilizer and grain facility in Union Mills,
the LaPorte County Sheriff's Department said.
     Initially, the Sheriff's Department said the explosion was
at a fertilizer plant. Later Shawn Lambert, the safety and risk
manager at Co-Alliance, said the explosion happened in a grain
silo at the facility. 
    The employee was working in the concrete grain silo that is
adjacent to a railroad spur at the time of the blast, according
to a post on the department's Facebook page. No other
information was released on the employee.
    All others who were at the plant at the time of the
explosion have been accounted for, according to LaPorte County
Sheriff's deputy Neil Lachmund.
    Lachmund said the cause of the blast is unknown.
    No hazardous chemicals were involved or released as a result
of the explosion and it is not believed that a fire was
involved, the post said.
    The facility is about 70 miles (113 km) southeast of
Chicago.
    Two months ago a fertilizer plant explosion in West, Texas
killed 14 people and injured about 200.
    Less than two weeks ago, an explosion and fire killed one
person and injured 73 at the Williams Olefins chemical plant in
Geismar, Louisiana.
