Son of a police chief in California has been arrested for assaulting a septuagenarian this week.

Tyrone McAllister, 18, is among the two teenagers arrested and charged with attempted robbery and abuse in the attack on a 71-year-old Sikh man named Sahib Singh Natt, reported news agency Press Trust of India.

It is not immediately known if the attack was a hate crime. Tyrone’s companion was a 16-year-old juvenile.

Tyrone is the son of Union City Police Chief Darryl McAllister.

Taking to Facebook, Darryl said he was “disgusted” to find out that one of the suspects was his son. According to him, the youngster has been estranged from the family for months now.

“Words can barely describe how embarrassed, dejected, and hurt my wife, daughters, and I feel right now,” Darryl said in the statement. “Violence and hatred is not what we have taught our children; intolerance for others is not even in our vocabulary, let alone our values.”

“In the eyes of the public, no matter the irrelevance to the incident, the fact remains that the father of the perpetrator of this despicable crime is a police chief, period,” he said.

Darryl said his son began to lose his way a few years ago after he started getting involved with a bad crowd. “He got into trouble for some theft-related crimes and ended up spending several months in juvenile hall. Since being released, he has been wayward and has not returned to our family home for several months,” he said.

Footage from a surveillance camera shows Natt walking alone on the side of a road early morning on August (6) when two men wearing hoodies approach him. The duo talks to Natt and they keep following him when he walks past them.

The trio have an argument and the 71-year-old is attacked by one of the men, who is wearing a hoodie. The elderly man falls down on the road, with his turban coming off. Although he tries to defend himself, Natt was unsuccessful in his attempts.
