MANTECA, Calif. – The 18-year-old son of a California Bay Area police chief, who is accused of attacking a 71-year-old Sikh man, appeared in court Friday, smiling and waving his middle fingers at media cameras, a report said.

Tyrone Keith McAllister, estranged son of Union City police Chief Darryl McAllister, entered the courtroom and flipped his middle fingers at their camera, Sacramento’s FOX 40 reported.

He appeared to be grinning, and made what were interpreted as gang signs while his hands were cuffed, the Record of Stockton reported.

“[W]ords can barely describe how embarrassed, dejected, and hurt my wife, daughters, and I feel right now,” the chief wrote on Facebook. Moreover, he also wrote that his son, who has spent time in both juvenile and adult jail, needs to be held accountable for his actions.

The younger McAllister and a 16-year-old companion allegedly confronted Sahib Singh Natt while he was taking a stroll in Manteca, near Stockton in the Central Valley, on Monday at about 6 a.m., and asked him for money.

Authorities said the pair kicked Natt to the ground. Police said the video shows the suspect kick him at least three times and that one of the suspects may have waved a gun.

The assault near Graystone Park was caught on a home surveillance camera.

The police chief and his wife worked with local police to track down their son and his 16-year-old accomplice. The pair were arrested Wednesday on one count of attempted robbery, elder abuse and assault with a deadly weapon.

“My family is shaken to the core,” Chief McAllister said. “It’s difficult for us to comprehend how one of three kids who grew up with the same parents, under the same roof, with the same rules and same values and character could wander so far astray.”

Natt is doing well after the attack but is too afraid to go on walks.

“The Sikh community, it has hit them hard but, you know, I would say that it’s not just the Sikh community, I think it hit the whole community of Manteca hard,” City council member and family friend Gary Singh said.

According to Judge Bob McNatt, McAllister also violated probation stemming from an April case in which he was arrested and spent three months in jail for battery and petty theft.

Detectives were still looking into whether the attack meets the legal criteria for charging a hate crime, the Record reported.

“As to whether it was just a crime or a hate crime, I’m of the opinion that at this point, looking at the videos, that it’s just a crime committed by some young people,” Bobby Bivens, president of the Stockton branch of the NAACP, told FOX 40.

Bail wasn’t set during the arraignment. McAllister was scheduled to appear again Aug. 17.
