The first investigation by New York City’s police inspector general includes the finding that in several cases where officers were found to have used a chokehold, the banned maneuver was the officer’s initial physical response to verbal resistance.

The 45-page report, released on Monday, follows the death in July of Eric Garner on Staten Island after an arresting officer placed him in a chokehold, a tactic that was banned by the Police Department two decades ago. The report looks at officers’ ongoing use of chokeholds and the department’s handling of such actions.

The inspector general’s office, created by the City Council over the objections of the Bloomberg administration, had been expected to release the report last month, but pushed back the date after two officers were fatally shot in their patrol car in Brooklyn on Dec. 20 by a man who was seeking to kill police officers and who killed himself minutes later.

Headed by Philip K. Eure, who was hired in May, the inspector general’s office examined the circumstances and the disciplinary actions that resulted in 10 confrontations between officers and suspects from 2009 to June 2014 in which a separate oversight agency verified that a chokehold had been used by an officer.
