ROCHESTER, N.Y. -- An officer is on administrative leave while the Rochester Police Department investigates if excessive force was used during a large melee at East and Alexander around 2 a.m. on April 14.

The officer was identified only as a 27-year veteran, who allegedly put a choke hold on a handcuffed person.

Some 200 people were involved in a fight, video of which made its way to the police chief and Mayor Lovely Warren, who the alleged victim contacted.

Police Chief Michael Ciminelli said there are 70 to 80 different angles of the free-for-all, thanks to police-worn body cameras. Police won't make any of the footage available.

Ciminelli said choke holds are considered a deadly force technique, prohibited for officers.

"We will not tolerate when protocol has not been followed. We will not tolerate when people are not doing the right thing, and I think that we will hold people accountable," said Warren, D-Rochester.

The FBI was also notified, because of potential civil rights violations.
