Bellevue's family, who spoke at a news conference Friday afternoon, said he has a history of mental illness and since the incident he has been "showing symptoms that he never showed before."
"He said to me, 'Judith, I cannot close my eyes. Every time I close my eyes I feel the officer choking me and I feel like I'm going to die,'" Bellevue's sister-in-law Judith Ceno said.
Bellevue's twin brother, Fritz, said since the incident, Ricky is not the same.
"He threatened me. I was scared for his life," Fritz Bellevue said. "He can't walk outside, he's scared."
NYPD officer in Queens chokehold surrenders to face charges
Bellevue's attorney Sanford Rubenstein said Bellevue was admitted to the hospital for both physical injuries and mental anguish.
"He was choked until he passed out. When someone gets choked until they pass out, they lose oxygen to their brain," Rubenstein said. "The extent of the brain damage he suffered at that time is something this hospital has to determine."
The NYPD officer who allegedly used the illegal chokehold surrendered to face charges Thursday.
Cell phone video showed officer David Afanadorperforming the banned chokehold Sunday in Rockaway Beach as police were trying to arrest a Bellevue who they say was threatening them.
After his arrest, Bellevue can be heard saying he's bipolar.
