THE BRONX - The family of a teen slashed at Lehman High School last month has announced a $5 million lawsuit against the Department of Education. 

Authorities say Powell and another student were involved in a fight, and Powell ended up with slashes across his faces. His family says he needed 20 stitches. 

The lawsuit claims that security at the school should have been more alert in the situation. 

News 12 reached out to the DOE, but it said it doesn't not comment on pending litigation.
