FALLSBURG - Union representatives are remaining tight-lipped about an elementary school heroin scandal.

Surveillance video shows Benjamin Cosor Elementary School teachers using a faculty bathroom where heroin and needles have been found twice since December. Now, seven teachers won't take drug tests.

Union representatives are allegedly advising the teachers not to take the drug tests. District Superintendent Dr. Ivan Katz told News 12 that this is because union contracts and state laws do not require the teachers to take drug tests at any time.

Angry parents pointed the finger at both the district and teachers unions during a Board of Education meeting Wednesday night. They say the Fallsburg School District is not a safe learning environment at the moment and the teachers need to be suspended.

The case is under investigation by both Fallsburg police and the Sullivan County District Attorney.
