All charges have been dropped against a Brooklyn postal worker who was arrested on the job after he yelled at police to slow down, according to District Attorney Ken Thompson. 

Glenn Grays was arrested on St. Patrick’s Day while delivering mail in Crown Heights.

Police say Grays got into a confrontation with officers after he claims he yelled at an unmarked police car that was speeding through the area to slow down.

Cellphone video shot by witnesses shows plain clothes officers arresting Grays after the alleged incident. 

Grays was issued a summons for being disorderly and resisting arrest. 

The police lieutenant who oversaw the arrest has been stripped of his gun and badge, according to the NYPD.
