MANTECA -- Home surveillance video shows a man kicked to the ground and spit on in a Manteca neighborhood.
Police in Manteca say the assault happened Monday morning in front of Graystone Park. Investigators say the attack was an attempted robbery, but 71-year-old man Sahib Singh Natt's family is calling it a hate crime.
Investigators said Wednesday they are still investigating whether or not the attack meets the requirements of being a hate crime. Police announced the arrest of 18-year-old Tyrone McAllister and a 16-year-old boy in connection with the assault.
The Manteca Police Department says McAllister is the estranged son of the Union City police chief.
McAllister has prior arrests in April for battery and a liquor store robbery.
Officers credited help from the public in the quick arrests.
Natt was on his daily walk around the park when he was approached by two men, one wearing a black hoodie, the other wearing a white hoodie.
"He was in such a shock. He was not able to tell us exactly what happened so he would tell us one thing and then he will mumble and say something else," relative Parminder Singh Sahi said.
Natt has had trouble communicating since an epileptic seizure seven years ago. Still, his family said the assault left him visibly upset.
"We were disheartened, we were shaken, it was way worse than what we were thinking may have happened to him," Sahi said.
In the video, Natt is seen walking away from the two men. The pair then blocks him, and the confrontation becomes violent.
"They kicked really hard, really hard," son-in-law Maneet Singh Virk said.
The man in the black hoodie kicks Natt to the ground. He gets back up, but the man kicks him again. Natt tries to fight back but he is kicked again.
Investigators with the Manteca Police Department believe one of the suspects had a gun.
The video shows the pair start to walk away as Natt is still on the ground, but the man in the black hoodie returns to kick him a few more times and spit on him.
"Just to hit him and spit on him," Sahi said. "That was disgusting."
Since Natt is unable to explain exactly what his attackers said, investigators are calling this an attempted robbery and not a hate crime.
Neighbors, disheartened by the attack, have posted flyers around the park.
"Just pains us and I felt like he needs to know, you know, and the family needs to know this is not our neighborhood, how this is," neighbor Michele Lazaro said.
Natt's family is grateful for the support and happy he is alive. They are especially appreciative of the man later seen walking his dog, who helps Natt to his feet and get home safely.
