THE WOODLANDS, Texas -

The building manager of 3 Waterway Square Place in The Woodlands says dozens of people were evacuated from the building because of a threat Friday morning.

We're told the threat was to an energy company in the building, but it affected at least one other business.

That other tenant, chemicals company Nexeo Solutions, told Local 2: "We dismissed our employees at approximately 10:00 a.m. after we were alerted to this threat by building management."

Employees tell us they were told to go home and not return until Monday.

Waste Connections, Inc., located on the ground floor, posted a memo on the front door saying they were closed until Monday as well.

Details surrounding the threat are unclear but it is under investigation.

No one was hurt.
