The Alameda County Sheriff’s Office is pursuing a battery charge against the Toronto Raptors’ top executive, who allegedly pushed a sheriff’s deputy and hit him in the face after the team clinched its first NBA championship Thursday with a win over the Golden State Warriors.

What should have been a moment of celebration for Raptors president and general manager Masai Ujiri, whose team dethroned the defending champion Warriors in their last game in Oracle Arena, turned into a tense standoff when a deputy denied him access to the court because he didn’t show a proper badge.

A shoving match ensued between Ujiri and the deputy, said Sgt. Ray Kelly, a spokesman for the Sheriff’s Office.

Ujiri was asked for the credential to get on the court, “and that’s when he tried to push past our deputy, and our deputy pushed him back, and there was another push that kind of moved up and struck our deputy in the face,” Kelly said. “Several bystanders intervened and the executive did ultimately get back onto the court without displaying credentials.”

Sheriff’s deputies took witness statements and obtained video of the incident, Kelly said.

“We’ll be submitting a report to the Alameda County district attorney for complaint of battery on an officer,” he said.

Teresa Drenick, the district attorney’s spokeswoman, said the office expects to receive the report next week.

“They are currently investigating and putting together their report,” she said. “My understanding is it will be submitted to the DA’s office sometime next week. They do not have a specific time. If and when it’s submitted, we will review it.”

Video of the altercation shows Ujiri holding a credential in his hand as a man gets between him and the deputy.

Ujiri pulled his credentials out after the physical confrontation, Kelly said.

“He had his credential on his body the whole time, which shows he could’ve produced it and we could’ve avoided this,” Kelly said.

Warriors season ticket holder Greg Wiener, who was at the game with his son, told USA Today that Ujiri had his credential in his hand by his side when he tried to get on the court. The deputy did not ask him for his credential before pushing him, Wiener said, which led Ujiri to respond by shoving the deputy “hard.”

Wiener said he didn’t see Ujiri hit the deputy in the face.

Ujiri is Nigerian and one of only a few black NBA executives, which has led people to question whether the deputy racially profiled him.

Kelly dismissed such criticism and noted that the deputy didn’t know Ujiri, the Raptors’ top club official.

“To turn this into a racial incident is completely inappropriate. This comes down to security and access based on credentials,” Kelly said. “It’s unrealistic for our officers to know who everybody is. To say that our deputies should have known who this person was defies why we have credentials in the first place.”

Security learned of Ujiri’s role with the team several minutes after the encounter and he was let onto the court after the game to celebrate with players and coaches.

“It’s not like we were going to chase him down,” Kelly said. “He had a right to be there, but he didn’t follow the credential policy.”

No arrest was made. The deputy reported pain in his face and jaw after the incident and was taken to the hospital, Kelly said. He has since been released.

“Any time you push a police officer in California, it’s a misdemeanor, battery of a police officer,” Kelly said. “We are trying to deal with it in a way that is manageable without stirring up too much, but that being said, you aren’t going to have someone push one of our officers and think they can just do that, no matter who you are.”

The Raptors issued a statement Friday saying the team was reviewing the incident and working with authorities.

“The incident is being looked at, and we are cooperating with authorities. We look forward to resolving the situation,” team officials said.

The NBA released a statement saying league officials were monitoring the situation.

“We are in contact with the Raptors and local authorities and in the process of gathering more information,” NBA spokesman Mike Bass said.
