The city's Department of Investigation Thursday released a report about a physical altercation between security staff at a migrant center and a former aide to the mayor, Tim Pearson.

The report — issued 16 months after the October 2023 incident — concluding that Pearson was the aggressor, not the victim he had claimed to be at the time.

"Pearson shoved and cursed at them," DOI Commissioner Jocelyn Strauber told NY1.

The report found Pearson, who had been a member of the NYPD before he advised Mayor Eric Adams on public safety matters, unjustifiably refused to show identification to security staff, then became physically aggressive.

Witnesses said he pushing one security guard, and then another, causing her to fall backward.

"Thereafter, [a] number of security guards moved him outside of the facility," Strauber said.

Then Pearson had the two security guards arrested. The report said the arrest was based on false reports from Pearson that they "manhandled" him as he entered the facility. The security guards were never prosecuted.

None of the altercation was captured on video. DOI investigators relied on witness testimony.

Pearson, who resigned in September, did not speak to DOI investigators, but his remarks after the altercation were captured on police body worn cameras saying the security staff, "started attacking me. I got my detective with me. We both came in here, and we were assaulted."

"Based on the overwhelming number of witnesses that we spoke to, that Pearson's version of events was not accurate," Strauber said.

NY1 was unable to contact Pearson. A lawyer who had represented him in a federal investigation did not return a request for comment.

Strauber said Pearson could have entered the migrant center — he just had to show identification.

"This was a totally avoidable situation, based on our findings," she said.
