The family of a Staten Island man who died after a confrontation with the police in July filed a claim on Tuesday announcing its intention to sue the city and several other parties.

The man, Eric Garner, 43, died on July 17 after he was wrestled to the ground by police officers arresting him for selling untaxed cigarettes.

A video of the encounter spurred widespread protests and prompted the police commissioner, William J. Bratton, to order a review of the department’s training and tactics regarding use of force.

The claim by the family was filed with the office of the New York City comptroller, Scott M. Stringer. It is the first formal step a plaintiff must take before suing the city.
