Two cops suffered head cuts last night when a goon hurled a glass vase off a rooftop as they tried to arrest a suspect after a dispute in The Bronx, sources said.

A housing cop called for backup and a borough anti-crime cop responded before they were hurt at Mount Eden and Morris avenues at 10:30 p.m.

One was taken to Bronx Lebanon Hospital and the other to St. Barnabas.

Both officers were treated and released.
