The Latest on sentencing of Silicon Valley mogul for probation violation in domestic violence case (all times local):

2:55 p.m.

A Silicon Valley internet mogul who made $300 million at the age of 25 has been sentenced to a year in jail for violating his probation in a domestic violence case.

Gurbaksh Chahal, now 34, was sentenced Friday by Superior Court Judge Tracie Brown, who gave him time to appeal the decision before starting to serve the sentence.

Chahal pleaded guilty in 2014 to misdemeanor charges of battery and domestic violence battery.

Prosecutors said surveillance footage showed him punching and kicking his girlfriend.

But the woman did not cooperate with authorities and a judge ruled the footage was improperly obtained and it was not allowed as evidence.

Prosecutors say Chahal violated his probation by attacking another girlfriend. The judge agreed in a ruling last month.

His attorneys in the probation case have challenged the credibility of the second woman.

Chahal made $300 million in 2007 when he sold his digital advertising company to Yahoo. A year later he appeared on "The Oprah Winfrey Show" in a segment that promoted him as a highly eligible bachelor.

A Silicon Valley Internet mogul who made $300 million at age 25 and appeared on "The Oprah Winfrey Show" is facing jail time for violating his probation in a domestic violence case.

San Francisco Superior Court Judge Tracie Brown is scheduled to sentence Gurbaksh Chahal on Friday.

Chahal pleaded guilty in April 2014 to misdemeanor charges of battery and domestic violence battery after prosecutors said surveillance footage showed him punching and kicking his girlfriend 117 times.

Prosecutors say he violated his probation by attacking a second girlfriend, and Brown ruled in their favor last month.

Chahal has defended himself against the domestic violence charges, saying he lost his temper but did not hit his girlfriend 117 times. His attorneys in the probation case have attacked the second woman's credibility.
